Abstract
Chromic potassium sulphate is found to be an efficient and recyclable catalyst for the selective oxidation of thiols to disulfides. The reaction was carried out in 60% methanol (v/v) using 30% H2O2 at room temperature. Cr(III) forms a complex with thiol which was then oxidized by H2O2 to produce disulfide in excellent yield after a simple workup procedure.
