Abstract: This study investigates the effects of 16- and 8-chloro substituents on catalytic activity of Fe( II), Co(II), and Cu(II) phthalocyanine (MCl16Pc and MCl8Pc) complexes in olefin epoxidation. The catalytic performance of these substituted catalysts has been tested for the oxidation of cyclohexene, cyclooctene, and styrene with iodosylbenzene and results have been compared with those of unsubstituted catalysts. In cyclohexene oxidation, epoxide selectivity (22-56% for MCl8Pc and 32-55% for MCl16Pc) is in order Fe(II) > Co(II) > Cu(II) complexes. In the catalytic oxidation of cyclooctene and styrene, only the corresponding epoxides have been obtained.
