A facile and selective method for oxidation of sulfides and thiols to their corresponding sulfoxides and disulfides with alumina-supported potassium permanganate under solvent-free conditions

Abstract

This paper describes the facile and selective oxidation of sulfides 1 and thiols 3 to their corresponding sulfoxides 2 and disulfides 4 with potassium permanganate supported on alumina in high yields under solvent-free conditions.
