Divinyl sulfide is the organosulfur compound with the formula S(CH=CH2)2. A colorless liquid with a faint odor, it is found in 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 bis(2-chloroethyl)sulfide with sodium ethoxide:[3]

(ClCH2CH2)2S + 2 NaOEt → (CH2=CH)2S + 2 EtOH + 2 NaCl

Monovinyl sulfides[edit]

With the formula CH2=CHSR, a variety of monovinyl sulfides are known. They often arise by the dehydrohalogenation of -2-haloethyl phenyl sulfides.[4] One example is phenyl vinyl sulfide.[5][6]
