Catalytic Conversion of Sulfides to Sulfoxides by the [PZnMo 2W9O39]5- Polyoxometalate

Abstract

Keggin type polyoxometalates can be used as catalysts for the activation of 30% aqueous hydrogen peroxide for the selective transformation of various organic substrates. In this paper, results are presented for the oxidation of sulfides to sulfoxides in high to excellent yields using 30% aqueous H 2O2 as oxidant and [PZnMo2W9O 39]5- as catalyst in acetonitrile.
