A Facile and Selective Method for Oxidation of Sufides and Thiols to Their Corresponding Sulfoxides and Disulfies with Alumina-Supported Potassium Permanganate Under Solvent-Free Conditions

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.
