Polymer – Supported Cobalt (II) Catalysts for the Oxidation of Alkenes

Abstract

Polymer-supported heterogeneous catalysts in a form of complexes of 8-hydroxy- quinoline with cobalt acetate were synthesized. Conjugated polymers – polyaniline (PANI), poly-o-toluidine (POT), poly-o-anisidine (POA) – were used as supports. Oxidation reactions of aliphatic and aromatic hydrocarbons were carried out in the presence of molecular oxygen at atmospheric pressure and epoxides or ketones were obtained as the main products with high selectivity.
