TETRABUTYLAMMONIUM PEROXYDISULFATE IN ORGANIC SYNTHESIS. XII.[1] A CONVENIENT AND PRACTICAL PROCEDURE FOR THE SELECTIVE OXIDATION OF THIOLS TO DISULFIDES WITH TETRABUTYLAMMONIUM PEROXYDISULFATE UNDER SOLVENT-FREE CONDITIONS

ABSTRACT

An efficient method for the oxidative coupling of thiols to their corresponding disulfide by (n-Bu₄N₂)S₂O₈ in high yields under solvent-free conditions is described. The reaction was applicable to a variety of thiols with high chemoselectivity.
