Applicability and mathematical verification of the reactivity–selectivity principle in the oxidation of thioanisoles by oxo(salen)manganese(V) complexes

Abstract

The second-order rate constants for the oxidation of various para-substituted thioanisoles with substituted oxo(salen)manganese(V) complexes have been measured spectrophotometrically in acetonitrile at 25 °C. Electron-withdrawing substituents in thioanisoles and electron-releasing substituents in oxo(salen)Mn^V complexes decrease the rate of oxidation. Correlation analyses show the presence of an inverse relationship between reactivity and selectivity in the reactions of various thioanisoles with a given oxo(salen)Mn^V complex and also in various oxo(salen)Mn^V complexes with a given thioanisole. Mathematical treatment of the results has also been carried out.
