The redox reaction of 2-trifluoromethylchromones with ethyl mercaptoacetate in the presence of triethylamine results in the formation of 1,2-dihydrothieno[2,3-c]chromen-4-ones and diethyl 3,4-dithiadipate in high yields. Oxidation of the first compounds w

The reactivity of photoactivated organocobaloxime was investigated by the reaction of thiol.Alkyl(pyridine)cobaloxime and ethyl mercaptoacetate were irradiated with a tungsten lamp under anaerobic conditions in an organic solvent to give ethyl alkylthioacetate, diethyl 2,2'-dithioacetate, and ethoxycarbonylmethylthiocobaloxime.Mechanistic investigations were carried out to determine the reaction course.Sulfide was assumed to be produced via a homolytic substitution between alkylcobaloxime and disulfide formed during the reaction.Disulfide was formed from thiol catalytically in the presence of cobaloxime under anaerobic conditions.Homolytic methyl-transfer scarcely occurred from methylcobaloxime into thiol.

Alkyl groups of alkylcobaloximes were transferred to alkylthiols by irradiation of alkylcobaloxime and thiol under anaerobic conditions; a radical route via homolytic substitution between alkylcobaloxime and disulfide, formed during the reaction, is proposed.

We report a reaction of the chlorofullerene C70Cl10 with thiols producing C70[SR]5H with all organic addends attached around one central pentagon at the pole of the C70 cage. This reaction was shown to proceed via a complicated radical pathway, presumably involving addition, substitution, rearrangement, and/or elimination steps. The obtained C70[SR]5H products were shown to be very unstable and undergo quantitative decomposition to pristine C70, RSSR, and RSH at elevated temperatures (e.g., 50 °C). Quantum chemical calculations and NMR spectroscopy data showed that cleavage of organic addends from the fullerene cage could be induced by solvation effects in solution.

Benzyltriethylammonium tetrathiomolybdate has been found to be a superior reagent for the conversion of alkyl halides to the corresponding disulfides in chloroform at room temperature.
Synthesis of Unsymmetrical Functionalised Organic Sulphides

Acyclic thioiminium salts and the condensed thiazolium salts in the presence of aqueous sodium hydroxide as such or under base catalyzed phase transfer catalysis conditions react with appropiate organic halides to provide corresponding unsymmetrical functionalized organic sulphides.With aqueous sodium hydroxide, thioiminium salts provide the disulphides corresponding to incipient thiol.
