Oxidation of chalcogenides using the peroxo complex of molybdenum [MoO(O2)2(H2O)(hmpa)], hmpa = hexamethylphosphoramide

Abstract

This work reports the oxidation of a variety of selenides, sulfides, tellurides, selenoxides, sulfoxides and telluroxides with [MoO(O2)2(H2O)(hmpa)] [hmpa = (Me2N)3PO] in tetrahydrofuran at 65-70 oC to produce the corresponding selenones, sulfones and tellurones in high yields. © 2009 Sociedade Brasileira de Química.
