Abstract

In the present work, an account of biomimetic oxidation, Mn(Br8TPP)Cl has been successfully bonded to imidazole modified polystyrene. Polystyrene-bound imidazole (PSI) is not only a heterogeneous axial base but also is a support for immobilization of Mn(Br8TPP)Cl. Mn(Br8TPP)Cl-PSI catalyzes alkene epoxidation with sodium periodate under agitation with magnetic stirring. Alkylaromatics and cycloalkanes were oxidized efficiently to their corresponding alcohols and ketones in the presence of this catalyst. Ultrasonic irradiation enhanced the catalytic activity of this catalyst in alkene epoxidation and alkane hydroxylation and this led to shorter reaction times and higher product yields. This new heterogenized catalyst is of high stability and reusability in the oxidation reactions.
