Sulfoxides and sulfones have broad applications in pharmaceutical agents and pesticide due to their biologically activities and they are important synthetic intermediates in C--C bond formation and various molecular rearrangements. The selective oxidation of sulfides is a straightforward and frequently used method to obtain sulfoxides and sulfones. Among vari- ous oxidizing agents, hydrogen peroxide as benign oxidant has attracted organic chemists＇ attention for a long time. This re- view summarizes the recent and important catalytic systems of metal and nonmetal in this area. The catalytic effect of different catalytic systems is briefly discussed herein.
