Mild Oxidation of Organosulfur Compounds with H2O2 over Metal-Containing Microporous and Mesoporous Catalysts

Mild catalytic oxidation of thioethers and thiophenes is an important reaction for the synthesis molecules with pharmaceutical interest, as well development efficient processes able to remove sulfur-containing pollutants from fuels wastewater. With respect green chemistry principles, hydrogen peroxide (H2O2) ideal oxidant Me-containing porous materials (Me = Ti, V, Mo, W, Zr) are among best heterogeneous catalysts these applications. The main classes catalysts, including Me-microporous mesoporous silicates, Me-layered double hydroxides, Me-metal–organic frameworks, described in this review. active species generated presence H2O2, probable mechanisms, also addressed. reactivity sulfoxidation process role played by solvents explored.
