- Catalytic synthesis of dialkyl sulfides from dialkyl disulfides
-
Dialkyl disulfides R2S2 where R = Me, Et, or Pr, both as individual compounds and as their mixtures, isolated from petroleum products can turn into alkanethiols and dialkyl sulfides under the action of catalysts having strong acid sites and medium-strength basic sites on their surface. In a helium atmosphere, the main conversion products are alkanethiols, while dialkyl sulfides form in low yield at a selectivity of no higher than 20%. A much higher dialkyl sulfide selectivity is attained in the reaction involving methanol. The most efficient catalyst for this reaction is alumina, with which the dialkyl sulfide selectivity is up to 99%.

- A catalytic synthesis of thiosilanes and silthianes: Palladium nanoparticle-mediated cross-coupling of silanes with thio phenyl and thio vinyl ethers through selective carbon-sulfur bond activation
-
Palladium nanoparticles generated in situ from N, N-dimethyl-acetamide (DMA) solutions of PdX2 (X = Cl-, OAc-, OCOCF3-) or Pd2(dba)3 by reduction with alkyl silanes R3SiH (R = Me, Et, i-Pr, t-Bu) are selective catalysts for the cross-coupling of the silanes R3SiH with phenyl and vinyl thioethers forming the corresponding thiosilanes and silthianes in high yields and under mild conditions. The method is applicable to phenyl thioglycosides, giving access to thiosilyl glycosides a new class of sugar derivatives.

- Inactivation of mitochondrial monoamine oxidase B by methylthio-substituted benzylamines
-
Mitochondrial monoamine oxidase was inactivated by o-mercaptobenzylamine (1) and o- (2) and p-methylthiobenzylamine (5). Experiments were carried out to provide evidence for possible mechanisms of inactivation. The corresponding o- (3) and p-hydroxybenzylamine (4) are not inactivators. Four radiolabeled analogues of 2 and 5, having radioactivity at either the methyl or benzyl groups, were synthesized, and all were shown to incorporate multiple equivalents of radioactivity into the enzyme. Inactivation in the presence of an electrophile scavenger decreased the number of molecules incorporated, but still multiple molecules became incorporated; catalase did not further reduce the number of inactivator molecules bound. Two inactivation mechanisms are proposed, one involving a nucleophilic aromatic substitution (SNAr) mechanism and the other a dealkylation mechanism. Evidence for both mechanisms is that inactivation leads to reduction of the flavin (oxidation of the inactivator), but upon denaturation the flavin is reoxidized, indicating that attachment is not at the flavin. A cysteine titration indicates the loss of four cysteines after inactivation and denaturation. Support for the S NAr mechanism was obtained by showing that o- and p-chlorobenzylamine also inactivate MAO. Chemical model studies were carried out that also support both SNAr and dealkylation mechanisms.

- Hydrosulfurization of methanol on Y2O3-TiO2-ZrO2 catalysts
-
Y2O3-TiO2-ZrO2 catalysts, where the contribution of oxide components ranges from 0 to 100 mol %, have been studied for their catalytic performance in methanol hydrosulfurization. Their activity and selectivity have shown a strong dependence on acid-base properties which, in turn, changed with catalyst composition. High yttria content favors selectivity to methanethiol, while catalysts highly active for the formation of dimethyl-sulfide were those containing 8 mol % Y2O3. The latter composition, which boosted selectivity to (CH3)2S, has created favorable conditions for the generation of acid centers in chemically mixed oxides as concluded on the ground of ESR studies and acidity measurements.

- Transformation of ethene into ketones by CO and H2over NiMo sulfide catalysts
-
The reaction of ethene, CO and H2 on NiMo sulfide catalysts at 240-290 °C and at 1 MPa gives ethane, diethyl ketone, propyl ethyl ketone, propanal and diethyl sulfide (DES). The support (carbon, alumina, magnesia and zirconia) influenced the activity of catalysts and the ratio between oxygenated and sulfur products. The carbon supported catalyst was the most active, producing the lowest proportion of DES. The overall oxo selectivity was practically constant in a broad range of ethene conversion. Selectivity into the formation of diethyl ketone increased by lowering the reaction temperature and H2S concentration in the feed. A selectivity of about 25% into diethyl ketone was achieved with a feed containing 0.4% H2S at 240 °C.

The reaction of bis(trifluoromethyl) disulfide with organolithium reagents at -78 deg C results in simultaneous scission of both the C-S and S-S bonds.Under similar conditions, the alkyl and aryl disulfides undergo only S-S bond cleavage.This unusual behavior of bis(trifluoromethyl) disulfide is due to the presence of the trifluoromethyl function.The product distribution, the mechanism of bond fission and the mass spectral data of compounds thus formed are presented in this paper.

- Radical Cations from One-electron Oxidation of Aliphatic Sulphoxides in Aqueous Solution. A Radical Chemical Study
-
Sulphoxide radical cations, (R2SO)+., have been observed upon one-electron oxidation of simple aliphatic sulphoxides by strongly oxidizing radicals with redox potentials >/=+2 V, e.g.SO4-., (CH3I)+., (CH3IICH3)+, or Ti2+ in pulse-irradiated aqueous solutions.They exhibit optical absorptions in the u.v. with λmax depending on the substituent (e.g. 300, 320, and 330 nm for R=Me, Et, and Pr, respectively).Extinction coefficients are of the order of 103 mol-1dm-3cm-1.The sulphoxide radical cations exist only at low pH and are probably best formulated in terms of an adduct with one water molecule, (R2SOOH2)+.The pK values for the equilibrium (R2SOOH2)+R2SO(OH). + H+ have been estimated to be 5.6, 6.1, and 6.5, for R=Me, Et, and Pr, respectively, from yield measurements.The neutral R2SO(OH). is identical with the hydroxyl radical adduct to sulphoxides formed at any pH in the reaction of R2SO + .OH, and decays irreversibly into R. + RSO2- + H+.The sulphoxide radical cationsare very good oxidants.Absolute rate constants have been measured for their reactions with a variety of electron donors, namely, organic sulphides, dithia compounds, disulphides, Br-, I-, and SCN-.The optical and kinetic results are discussed in the light of the electronic properties of the radical species.

- Electronic and steric effects in the dissociative displacement of thioethers from mixed phenyl(thioether)platinum(II) complexes
-
A series of compounds of the type cis-[PtPh2L2], where L encompasses a wide range of thioethers of different steric and electron-donating characteristics, have been prepared and characterized. Most of these monomeric compounds exist in solution in equilibrium with the sulfur-bridged dimer [Pt2Ph4(μ-L)2] and the free thioether. Addition of small amounts of ligand in solution allows the stabilization of the monomeric form. Kinetic studies of the displacement of the thioethers with 2,2′-bipyridine (bpy) to yield [PtPh2(bpy)] in CH2Cl2 at 298.16 K, carried out in the presence of sufficient excess of [L] and [bpy] to ensure pseudo-first-order conditions, showed that the reactions follow a bivariate nonlinear rate law kobsd = a[bpy]/(b[L] + [bpy]) + c[bpy], which has the same form as that of similar systems for which a dissociative mechanism has been proposed. The reactivity decreases linearly with increasing σ-donor ability of the leaving thioether, with bulky substituents on sulfur playing an accelerating role. The relative sensitivities of the dissociative and associative processes to the inductive effects of the leaving group are compared and related to the degree of lengthening and weakening of the bond with the metal produced by the trans-activating group.

- Catalyitic Decomposition of Mercaptans on Metal Films of Iron, Nickel, Palladium, Aluminium and Copper
-
Adsorption and decomposition of methanethiol and n-propanethiol on clean and oxidized films of Fe, Pd, Ni, Al, and Cu have been studied in the temperature range 193-500 K.Mainly molecular chemisorption of mercaptans occured on the films at 193 K.All the mercaptans were chemisorbed dissociatively on all surfaces above 300 K by the rupture of S-H, C-S, C-H,and C-C bonds.The proposed dominant pathway involved decomposition of the mercaptan to form a thiolate (-SR) on a surface site and a hydrogen adatom on the adjacent site.In another less important pathway, sulphhydryl (-SH) and alcyl groups are formed.Surface recombination reactions of the bound species took place at temperatures >300 K yielding hydrogen, hydrocarbons together with some alcyl sulphide.The gasous products subsequent to the decomposition of the mercaptans on the oxidized metal films also involved other gases, including CO, H2O and olefins.The pattern of the products formed and their relative concentrations at temperatures 300-500 K indicated that the extent of mercaptan dissociation decreased in the order S-H, C-S > C-H > C-C.The rate of mercaptan adsorption directly depended on its pressure and the kinetic data revaled the operation of a compensation effect throughout the interaction of the mercaptan with various films.The transition-metal films showed greater activity than Al and Cu, and among the former metals Fe exhibited the greatest activity for mercaptan adsorption.

- REACTION OF THIOACETALS WITH TRIETHYLSILANE IN THE PRESENCE OF LEWIS ACIDS AND REDUCED NICKEL
-
1,1-Di(alkylthio)alkanes, 1,3-oxathiolanes, 1,3-dithiolanes, and ortho thioesters are cleaved by triethylsilane in the presence of catalytic amounts of zinc iodide or reduced nickel.In the presence of zinc iodide the acyclic dithioacetals and ortho thioester are converted into alkyl sulfides and triethyl(alkylthio)silanes by cleavage of the carbon-sulfur bond.The analogs of the cyclic acetals are cleaved by triethylsilane only in the presence of reduced nickel, while regiospecific cleavage of the heterocycle at the carbon-oxygen bond is observed in 1,3-oxathiolanes.The cleavage of the 1,3-dithiolanes takes place by a more complicated mechanism with the formation of the disilyl ether of ethanediol, hexaethyldisilylthiane, and triethyl(alkylthio)silanes.The cyclic ortho thioester reacts with triethylsilane both at zinc iodide and at reduced nickel with the formation of the products from preferential cleavage of the exocyclic bond.

- INFLUENCE OF CRACKING OF THIOLS ON ZEOLITE LIFE DURING REMOVAL OF SULFUR COMPOUNDS FROM NATURAL GAS BY ADSORPTION.
-
The purpose of this work was to study the kinetics of coke deposition of NaX zeolite as the result of decomposition of ethanethiol and to estimate the loss of the adsorption capacity of the zeolite due to coking. Despite their great interest, these questions have not received adequate attention in the literature. It is shown that the rate of coke accumlation in the zeolite drops sharply with decrease of temperature and the process virtually stops at 200 degree . Accordingly, in order to lengthen the service life regeneration of the zeolite should be conducted in two stages, with desorption of most of the thiols at 200-220 degree , followed by increase of the bed temperature to 300-320 degree .

- RADICAL CATIONS OF ORGANIC SULPHIDES AND DISULPHIDES FORMED BY RADIOLYSIS: AN ELECTRON SPIN RESONANCE STUDY
-
Exposure of dilute solutions of various organic sulphides in fluorotrichloromethane at 77 K to 60Co γ-rays gave species identified by their e.s.r. spectra as the parent radical cations.The average β-proton coupling (R2CHS.R)+ of ca. 20 G is about half that for the corresponding ether cations, indicating greatly reduced ?-? delocalisation.However, the spread of g-values (ca. 2.032, 2.015, 2.00) is much greater than that for the ether cations.These cations readily react with other disulphide molecules to form (R2S.-SR2)+ dimer cations.The spectrum for tetrahydrothiophene (tetramethylene sulphide) exhibits a large coupling to two axial protons (ca. 42 G) and two equatorial protons (ca. 19 G), the coupling constants again being about half those for tetrahydrofuran cations.However, conformational inversion did not occur below the softening point of the solids (ca. 160 K) in marked contrast with the ether cations.The three-and four-membered ring cations (ethylene and trimethylene sulphide cations) gave very similar spectra with gx = gy, and four equivalent protons having an isotropic coupling of ca. 31 G.Thus their structures are similar to the normal R2S.+ cations, the equivalence of the g-values being interpreted in terms of effective C-S-C bond angles (θ) close to 90 deg.This, in turn, implies that θ > 90 deg for the unconstrained cations.It is noteworthy that the ethylene oxide (oxirane) cation exhibits a smaller coupling to its four protons (16 G).This implies a drastic change in structure for the oxirane cation which is clearly not the case for the sulphur analogue.Disulphides of structure R-S-CH2-S-R form cyclic ?* radicals with weak S-S bonding, in marked contrast with the oxygen analogues (acetal cations) which have ?-structures conferring very high spin-density onto the CH2 protons.Other molecules containing two RSR units form similar cyclic ?* radicals.Persulphides of structure RS-SR readily give the ?-cations (RS.SR)+, characterised by g-values in the region of 2.035, 2.018, 2.002.The smaller range of g values for (PhS.-SPh)+ cations is interpreted in terms of ca. 30percent spin-delocalisation into both the benzene rings.

- Phase-Transfer-Catalyzed Oxidation and Reduction of Organosulfur Compounds with Dichlorocarbene. Mechanism and Synthetic Utility
-
Diaryl and dialkyl sulfoxides undergo facile phase-transfer-catalyzed (PTC) deoxygenation with dichlorocarbene at 25 deg C to afford excellent yields of sulfides.Comparisons of deoxygenation rates of dialkyl and diaryl sulfoxides suggest that steric acceleration occurs with the bulky sulfoxides while resonance interactions from aromatic rings retard the reduction.Less bulky sulfides also undergo the reverse reaction: addition of dichlorocarbene to the sulfide with hydrolysis of the dialkyl dichloromethylide with hydroxide ion to afford the corresponding sulfoxide. "Oxidation" of trans-thiadecalin by reaction with PTC dichlorocarbene addition followed by basic hydrolysis is highly stereoselective, affording 94 percent axial and 6 percent equatorial sulfoxide.
