Reactions ofβ, β-dichlorovinyl organyl sulfides with thiols and the synthesis of bis(organylthio)acetylenes

Conclusions ,-Dichlorovinyl organyl sulfides can react with thiols and KOH by several pathways, depending on the conditions, leading to different unsaturated sulfides. We have found a simple preparative route to bis(alkylthio)acetylenes with identical or different radicals.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 426–431, February, 1978.We thank V. V. Keiko for the preparative separation of isomers (I) and (III).
