Reactions of Benzenesulphenyl Chloride with α,β-Unsaturated Compounds: Part III - Reactions with Maleic Anhydride

The interaction of maleic anhydride (2) and benzenesulphenyl chloride (1) in the presence of pyridine gives 1,2-bis(phenylthio)maleic anhydride (3) as the sole product.Monophenylthiomaleic anhydride (4) on the other hand, is the only product of the reaction between 2 and 1 in the presence of triphenylphosphine (13).Some aspects of the mechanism of these two reactions have been discussed.
