A Novel and Efficient Synthesis of Unsymmetrical Disulfides

Abstract

Unsymmetrical disulfides have been prepared from the corresponding thiols and bis-(5,5-dimethyl-2-thiono-1,3,2-dioxa­phosphorinanyl)disulfide under mild conditions with good to ex­cellent yields. The method can be applied to thiols bearing neutral, aromatic, basic or acidic functionalities with variable length of carbon chain.

Key words

unsymmetrical disulfides - alkanethiols - l-cysteine - thiophenol
