                           The nitroso group transfer from N-nitrososulfonamides to thiolate ions was studied. Based on the results, the reaction rate
                           is strongly dependent on the nature of the leaving group (alg˜-1.30), but virtually independent of the basicity of the thiol
                           (ßnuc˜0.10). This dependence is ascribed to the presence of a nucleophile desolvation equilibrium (ßd) that is followed by
                           the attack of the thiolate ion on the nitroso group  via a concerted mechanism. The equilibrium constants for the loss of
                           a nitroso group from a nitrosothiol and an N-nitrososulfonamide were used to obtain the equilibrium constants for the different
                           reactions involved. By using rate–equilibrium correlations, the parameters , ßd, and  were obtained.

                           A kinetic study has been carried out on nitroso group transfer from substituted N-methyl-N-nitroso-benzenesulfonamides to
                           different secondary amines: pyrrolidine, piperidine, N-methylpiperazine, and morpholine in cyclohexane. The observed pseudo-first-order
                           rate constant kobs shows a linear and quadratic dependency on the amine concentration with the existence of a primary kinetic
                           isotope effect. Experiments carried out at different temperatures show Arrhenius-type behavior. Addition of isopropylamine
                           (iPrNH2) to the reaction medium produces an increase in kobs. In the presence of a high iPrNH2 concentrations the influence
                           of secondary amine concentration on kobs shows the disappearance of the quadratic dependency of kobs on the secondary amine.
                           These results would be compatible with an addition-elimination mechanism, similar to that observed for the aminolysis of the
                           alkyl nitrites in apolar solvents. The observed behavior in the presence of 18-crown-6 is very different, however. Addition
                           of crown ether catalyses the reaction of aminolysis of alkyl nitrites insofar as it does not alter the rate of the nitroso
                           group transfer from N-nitrososulfonamides. This behavior has been interpreted in terms of a concerted reaction mechanism through
                           cyclical transition states, with four or six centers, involving one or two molecules of secondary amine. Addition of iPrNH2
                           to the reaction medium causes the appearance of a third reaction path, which emerges through a mixed transition state formed
                           by a molecule of a secondary amine and a molecule of isopropylamine. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim,

"Dichloro and dimethyl dioxomolybdenum(VI)–diazabutadiene complexes as catalysts for the epoxidation of olefins", New Journal of Chemistry 2004, 28: 308 - 313. Abstract
                           
                           The dioxomolybdenum(VI) complex [MoO2Cl2{p-tolyl(CH3DAB)}] has been prepared in good yield by reaction of the solvent adduct
                           MoO2Cl2(THF)2 with one equivalent of the bidentate ligand N,N-p-tolyl-2,3-dimethyl-1,4-diazabutadiene. Treatment of the dichloro
                           complex with the Grignard reagent CH3MgCl gives the dimethyl derivative [MoO2(CH3)2{p-tolyl(CH3DAB)}]. The complexes are highly
                           active and selective catalysts for the homogeneous epoxidation of cyclooctene using tert-butyl hydroperoxide (TBHP) as the
                           oxidant. In both cases, the initial activity is ca. 175 mol mol–1Mo h–1 and cyclooctene oxide is obtained quantitatively within
                           4 h. It was possible to recover the dimethyl complex at the end of the reaction and reuse it in a second run with only a small
                           decrease in activity. The complexes are also active and selective for the epoxidation of other olefins, such as 1-octene,
                           2-octene, cyclododecene and (R)-( )-limonene, with TBHP. The catalytic production of cyclooctene oxide was investigated in
                           detail, varying either the reaction temperature or the initial concentrations of substrate, oxidant and catalyst precursor.
                           Kinetic studies show that the catalyst precursor–oxygen donor complex formation is first-order in TBHP and in the metal complex
                           [MoO2Cl2{p-tolyl(CH3DAB)}]. A specific rate of 3.2 mol–1 dm3 s–1 was found for catalyst formation at 25°C. Activation parameters
                           for this reaction have also been measured (H=48±3 kJ mol–1, S=–112±10 J mol–1 K–1).

"Mechanism for Basic Hydrolysis of N-Nitrosoguanidines in Aqueous Solution", The Journal of Organic Chemistry 68, 11: 4330 - 4337. Abstract
                           
                           A kinetic study was carried out on the hydrolysis of two N-nitrosoguanidines, 1-nitroso-1-methyl-3-tolylsulfonylguanidine
                           (TSGNO) and 1-nitroso-1-methyl-3-benzoylguanidine (BCGNO). We observed an absence of buffer catalysis using H2PO4-/HPO42-,
                           H3BO3/H2BO3-, and HCO3-/CO32- regulators and a complex dependency of the rate constant on the pH. We discovered the existence
                           of three simultaneous reaction paths:  spontaneous decomposition of the neutral form of the N-nitrosoguanidine, decomposition
                           of the monoanion, and decomposition through the form of the dianion. The analysis of the kinetic data has allowed us to obtain
                           the acidity constant for the formation of the monoanion of the N-nitrosoguanidine, with values of p  = 11.5. The reaction
                           rate for the process through the monoanion, k2, decreases as the acidity increases. The application of the principle of nonperfect
                           synchronization shows that the basicity and reactivity do not correlate when there exists a possibility of stabilization of
                           the negative charge by resonance. This behavior is consistent with the mechanism E1cB whereby the stabler the negative charge,
                           the slower the elimination reaction. When dealing with the case of the elimination through the neutral form we observe that
                           the reaction rate increases together with the capacity of stabilization of the positive charge on the nitrogen atom adjacent
                           to the imino group. For the reaction through the dianion we used a maximum value of k3 = 1010 s-1 to estimate the value of
                           p for the formation of the dianion of the N-nitrosoguanidine, obtaining values of p  < 24.

Intrinsic and Apparent Reactivity", The Journal of Organic Chemistry 66, 2: 381 - 390. Abstract
                           
                           We have studied the nitroso group transfer from substituted N-methyl-N-nitrosobenzenesulfonamides to primary and secondary
                           amines, observing that the rate of the reaction increases as a consequence of the presence of electron withdrawing groups
                           on the aromatic ring of the nitrosating agents. The rate constants determined for the nitroso group transfer, ktr, give good
                           Bronsted-type relationships between log ktr (rate constant for nitroso group transfer) and p  and p    . The study of the
                           nitrosation processes of secondary amines catalyzed by ONSCN and denitrosation catalyzed by SCN-, in combination with the
                           formation equilibrium of ONSCN, has enabled us to calculate the value of the equilibrium constant for the loss of the NO 
                           group from a protonated N-nitrosamine (p  ), which can be defined by analogy with p  . The value of p  for the loss of the
                           NO  group from an N-methyl-N-nitrosobenzenesulfonamide was obtained in a similar way. By using values of ¿pKNO = p  - p  ,
                           we were able to calculate the equilibrium constant for the nitroso group transfer and characterize the transition state. On
                           the basis of Bronsted-type correlations, we have obtained values of  and    0.55, showing a perfectly balanced transition
                           state. In terms of the Marcus theory, the calculation of the intrinsic barriers for the nitroso group transfer reaction shows
                           that the presence of electron withdrawing groups on the aromatic ring of the N-methyl-N-nitrosobenzenesulfonamides does not
                           cause these barriers to vary.

                        on the Solvolysis Mechanism of Substituted Benzoyl Chlorides", Journal of the American Chemical Society 122, 42: 10325 - 10334. Abstract
                           A study was carried out on the solvolysis of the following substituted benzoyl chlorides in sodium bis(2-ethylhexyl)sulfosuccinate
                           (AOT)/isooctane/water microemulsions:  4-CH3O, 3,4-(CH3O)2, 4-CH3, 4-H, 4-Cl, 3-Cl, 4-CF3, 3-CF3, 3-NO2, and 4-NO2. The benzoyl
                           chlorides are found distributed between the isooctane and the interface, where they react with its hydration water. From the
                           kinetic data we have been able to obtain the true rate constant for the reaction at the interface, ki. Two extreme types of
                           behavior have been observed:  for those processes which occur via a predominantly dissociative pathway, ki decreases together
                           with W (W = [H2O]/[AOT]), while for those processes which occur through a predominantly associative pathway, the rate constant
                           at the interface, ki, increases as W decreases. The decrease of ki with W is interpreted as being due to the capacity of interfacial
                           water for solvating the leaving Cl-. For the associative process, the increase in the nucleophilic capacity of the interfacial
                           water as W decreases is the factor responsible for the increase in ki, so that the lesser capacity for solvation of the transition
                           state can be compensated for as the water content of the microemulsion decreases. A comparative analysis of the reactivity
                           of substituted benzoyl chlorides at the interface of the microemulsion shows an increase of the rate of the associative pathway
                           and a decrease of the dissociative counterpart. Hence for W = 50, the change between the two reaction pathways is observed
                           for the benzoyl chlorides with substituents 4-Cl and 3-Cl, while in bulk water this change takes place with more electron-attracting
                           substituents. When the water content of the microemulsion decreases (W = 2), only the benzoyl chlorides 4-CH3O and 3,4-(CH3O)2
                           will react predominantly through the dissociative pathway.

                        Rate Constants  for the Deprotonation of Cationic Ketones by OH-  ", Journal of the American Chemical Society 121, 8: 1674 - 1680. Abstract
                           
                           Despite the central importance of monoketones as carbon acids, no intrinsic barriers or intrinsic rate constants for proton
                           transfer to a standard family of bases such as amines have been reported. This paper presents the results of such determinations
                           for the reaction of 2-acetyl-1-methylpyridinium ion (1) with secondary alicyclic amines. They yield log ko = 0.92 in water
                           and log ko = 1.70 in 50% DMSO-50% water (v/v) at 20 °C. These intrinsic rate constants are lower than for any sterically unhindered
                           carbon acids except for nitroalkanes, reflecting the strong p-acceptor character of the CO group as well as the strong solvation
                           of the oxygen in the enolate ion. Rate constants,  , for deprotonation of 1 by OH- have also been determined in water and
                           50% DMSO-50% water, with somewhat different results than those reported by Tobin and Frey (J. Am. Chem. Soc. 1996, 118, 12253).
                           The  value in water shows a small positive deviation from a correlation of such rate constants with the corresponding pKa
                           of 17 simple monoketones and aldehydes reported by Keeffe and Kresge; this deviation as well as the much larger positive deviation
                           for the deprotonation of 1-methyl-3-pyridinioacetophenone (7) and 1-pyridinioacetophenone (8) can be attributed to electrostatic
                           effects resulting from transition-state imbalance.

                           The reactions of N-methylaniline (MeAn) with 2,2-dichloroethylnitrite (DCEN) and 2,2,2-trichloroethylnitrite (TCEN) in cyclohexane,
                           and N-methylmethoxyamine (MMA) with TCEN in the same solvent, all gave the expected N-nitrosamines. Spectrophotometric monitoring
                           of the MeAn/DCEN and MMA/TCEN reactions showed accumulation of the reaction intermediate. These are the first nitrosations
                           of amines by alkyl nitrites in which observation of the intermediate has been possible; this is attributed to the low basicity
                           of these amines (a) having effectively eliminated the possibility of the intermediate decomposing by base catalysis and (b)
                           having decreased the rate of spontaneous decomposition of the intermediate more than the rate of its formation. Because of
                           the scant capacity of cyclohexane to stabilize charge, it is assumed that both the formation and decomposition of the intermediate
                           occur via concerted mechanisms with four-center transition states:  formation through nucleophilic attack by the amine on
                           the nitroso group accompanied by transfer of the amine proton to this group, decomposition through simultaneous cleavage of
                           the N-O bond, and protonation of the alkoxide leaving group.

Kinetics of acid hydrolysis of 1-methyl-1-nitroso-3-p-tolylsulfonylguanidine 2 and of two 1-methyl-1-nitroso-3-benzoylguanidines
                           (4-unsubstituted and 4-chloro) 5 and 6 have been studied. For the acid hydrolysis of 1-methyl-1-nitroso-3-p-tolylsulfonylguanidine
                           2, the absence of catalysis by thiocyanate ion, and the value of the kinetic solvent isotope effect indicate that either a
                           rate determining proton transfer followed by fast denitrosation or a concerted pathway is involved in the mechanism. In the
                           case of the acid hydrolysis of 1-methyl-1-nitroso-3-benzoylguanidines 5 and 6 it was observed that the protonated form decomposes
                           via two parallel pathways. One involves a slow nucleophilic attack concerted with an intramolecular proton transfer, and the
                           other a slow concerted denitrosation, where a second proton transfer and NO  expulsion are simultaneous. .

Evidence of an imbanlaced concerted mechanism", Journal of Chemical Society, Perkin Transactions 2, 1998: 1613 - 1620. The kinetics of the nitrosation reaction of several substituted sulfonamides and of the denitrosation of the resulting products
                           have been studied. The denitrosation rate is first-order with respect to both the nitroso compound and acid concentration
                           and no effect of added nucleophiles was observed. The denitrosation reaction is general-acid catalysed, with a Brønsted parameter,
                           d, of 0.7, which is independent of the substituents on the aromatic ring. Kinetic solvent isotope effects range from kdH3O
                           /kdD3O  = 1.20 ± 0.05 to 2.04 ± 0.06 for denitrosation by L3O  and from kdAH/kdAD = 1.5 ± 0.2 to 2.3 ± 0.3 for denitrosation
                           by dichloroacetic acid, which suggest that a rate-determining proton transfer is involved in this reaction. For nitrosation
                           reaction, the absence of catalysis by nucleophilic anions, the observed general-base catalysis (NO = 0.3) and the substituent
                           effects suggest a concerted nitrosation–denitrosation process. The Leffler parameters obtained for N· · ·H bond formation
                           (nuc = 0.7) as well as for N· · ·NO bond breaking (lg = 0.17) are in favour of an imbalance in the transition state (imbalance
                           = 0.53) with the development of a positive charge on the nitrogen adjacent to the nitroso group. .

                           A series of substituted N-methyl-N-nitrosobenzenesulfonamides [2,4,6-(CH3)3, 4-CH3O, 4-CH3, 4-Cl and 4-NO2] were synthesized.
                           All of them transfer their nitroso group to N-methylaniline in a quantitative manner, the more reactive being those substituted
                           with electron-withdrawing groups, thus resembling some of the known alkyl nitrites. Studies of their acid denitrosation and
                           base-catalysed hydrolysis demonstrated that the nitrosobenzenesulfonamides are fairly stable in aqueous media between pH 2
                           and 11. Their relative stability in aqueous media together with their ability to transfer the nitroso group to nucleophiles
                           suggest their use as excellent alternatives to alkyl nitrites in both neutral and basic media.
