Divinyl sulfide is the organosulfur compound with the formula S(CH=CH₂)₂. It is a colorless liquid with a faint odor. It is found in the oil of some species of Allium.^[1]^[2]

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.^[3]

Divinylsulfide was first prepared in 1920 by the reaction of sulfur mustard with sodium ethoxide:^[3]

(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.^[4]
