Divinyl sulfide
Divinyl sulfide is the organosulfur compound with the formula S(CH=CH). It is a colorless liquid with a faint odor. It is found in the oil of some species of "Allium". It is notable as the product from hydrogen sulfide and acetylene, a combination that arises when acetylene is generated by hydrolysis of technical-grade calcium carbide, which contains impurities of calcium sulfide. Divinylsulfide was first prepared in 1920 by the reaction of sulfur mustard with sodium ethoxide: A variety of monovinyl sulfides are known, often arising from the reactions of thiols and acetylenes.
