Abstract

A method of synthesis of organic mono-, di-, and polysulfides based on electrochemical reactions of unsubstituted and alkyl–substituted cycloalkanes C5–C8 with di(n-butyl)disulfide (di(tert-butyl)disulfide) and hydrogen sulfide is developed. Three–component electrosynthesis is carried out in methylene chloride under atmospheric pressure, at the room temperature under the conditions of anodic H2S activation to a cation radical fragmented to a proton and a thiyl radical. The suggested approach with application of oxidative conversion initiation allows obtaining asymmetric mono-, disulfides and symmetric disulfides. The yield of biologically active organic sulfur derivatives depends on the electrosynthesis duration, structure of isomeric dibutyl sulfides, alicycle size and saturation degree.
