Episulfide

[1] A number of chemists in the early 1900s, including Staudinger and Pfenninger (1916), as well as Delepine (1920) studied episulfides.

[3] In 1934 Dachlauer and Jackel devised a general synthesis of episulfides from epoxides using alkali thiocyanates and thiourea.

Following the lead of Dachlauer and Jackel, contemporary routes to episulfides utilize a two-step method, converting an olefin to an epoxide followed by thiation using thiocyanate or thiourea.

[5] Common uses of episulfides in both academic and industrial settings most often involve their use as monomers in polymerization reactions.

Nucleophiles include hydrides, thiolates, alkoxides, amines, and carbanions.
