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 very good yields. This method can be applied to thiols bearing neutral, aromatic, basic or acidic functionalities with variable length of carbon chain.
