α-Ketosulphides of benzothiazol 1 react with allylic carbonates in the presence of palladium acetate in dichloromethane under mild conditions affording α- and α,α-diallylated ketosulphides 2 in high yields. Reductive desulphurization of 2a-d with tributyl
Aminium Salts Induced Desulphurization of Allyl and Diallyl Thiiranes. Synthesis of Dienes and Trienes

Catalytic amounts of aminium salts A-B induce the conversion of methylene chloride in solutions of several allyl and diallyl episulphides 1-6 into the corresponding unsaturated derivatives 7-12.The desulphurization process, which occurs through a plausible chain electron-transfer mechanism, rapid and may proceed in a fashion that preserves the stereochemistry of the starting episulphide.
Palladium-catalysed Synthesis of α-Diallylated Ketosulphides of Benzothiazole and their Transformation into Diallyl Thiiranes and Trienes
Calo, Vincenzo,Fiandanese, Vito,Nacci, Angelo,Scilimati, Antonio
, p. 171 - 174 (2007/10/02)
α-Ketosulphides of benzothiazole 1 react with allylic carbonates in the presence of palladium acetate in dichloromethane under mild conditions affording α,α-diallylated ketosulphides 2 in high yields.Reduction of 2 with sodium borohydride in isopropanol gives episulphides which in turn can be transformed almost quantitatively into trienes.
