1,3-Dithietane
1,3-Dithietane is a dithietane. It is a colorless, crystalline, unpleasant-smelling solid. It was first prepared in 1976 by the reaction of bis sulfoxide with sodium sulfide to give 1,3-dithietane 1-oxide, followed by THF-borane reduction.
Examples of compounds bearing this functional group include the antibiotic Cefotetan and the pesticide Fosthietan. Desaurins are a type of 1,3-dithietanes with alkylidene groups attached to the two carbon atoms.
