Abstract Di (1-alkynyl) sulfides and the corresponding sulfoxides are obtained in high yields from lithium alkynides and sulfur dichloride or thionyl chloride, respectively. The di (1- alkynyl) sulfoxides and also the corresponding sulfones (prepared by oxidation of di (1- alkynyl) sulfides with m-chloroperbenzoic acid) react very rapidly with disodium sulfide, selenide or telluride to form six-membered heterocyclic compounds.
