Description 346-351
The kinetics of (salen)Mnˡˡˡ complexes-catalysed oxidation of a few diphenyl sulphides by hydrogen peroxide have been investigated at 25oC in acetonitrile (80%) – water (20%) spectrophotometrically. The reaction follows first-order kinetics in (salen)Mnˡˡˡ complex and zero-order kinetics in hydrogen peroxide. The order of the reaction with respect to sulphide is fractional. The effects of nitrogenous bases, free radical inhibitor and changes in solvent composition have also been studied. A suitable mechanism involving a manganese(III)-hydroperoxide complex as reactive species has been proposed.
