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

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.
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.
