Oxidation of Organic Compounds by Sulfonated Porous Carbon and Hydrogen Peroxide

The oxidation of organic compounds by sulfonated porous carbon and H2O2 was studied at room temperature. Alkyl and aryl sulfides were oxidized to the corresponding sulfoxides or sulfones in excellent yields. Secondary alcohols were also converted to the corresponding esters/lactones and aldehydes to methyl esters in good yields. Moreover, aliphatic tertiary amines and substituted pyridines were oxidized to N-oxides.

Sulfonated porous carbon and H2O2 were found to be highly efficient media for the oxidation of sulfides to sulfoxides or sulfones, tert-amines to N-oxides, secondary alcohols to esters/lactones, and aldehydes to methyl esters under mild conditions.Figure optionsDownload as PowerPoint slide
