Divinyl sulfide is the organosulfur compound with the formula S(CH=CH2)2. It is a colorless liquid with a faint odor. 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.[1]
Divinylsulfide was first prepared in 1920 by the reaction of sulfur mustard with sodium ethoxide:[1]
- (ClCH2CH2)2S + 2 NaOEt → (CH2=CH)2S + 2 EtOH + 2 NaCl
A variety of monovinyl sulfides are known, often arising from the reactions of thiols and acetylenes.[2]
