Sulfamic Acid–Catalyzed Oxidation of Sulfides to Sulfoxides and Sulfones Using H2O2: Green and Chemoselective Method

Abstract A mild, efficient, green, and selective oxidation method of sulfides to sulfoxides or sulfones using H2O2 in the presence of catalytic amounts of sulfamic acid has been developed. Various substituted sulfides having functional groups such as alcohol, ester, and aldehyde are successfully and selectively oxidized without affecting the sensitive functionalities in good to excellent yields at room temperature.
