Synthesis and catalytic performance of hydrophobic metalloporphyrins

Abstract

A new type of symmetric metalloporphyrins appended with long chain alkyl groups as hydrophobic groups has been synthesized and their catalytic performance in the epoxidation of styrene in CH2Cl2/H2O two-phase system has been studied. The results of epoxidation of styrene shown that the pH value of the aqueous phase plays an important role in the epoxidation; the influence of hydrophobicity of metalloporphyrins on the catalytic reaction is very small and the order of catalytic activity of hydrophobic metalloporphyrins is Mn>Co>Ni>Cu.

Key words: PORPHYRIN, STYRENE, MANGANESE COMPLEX, CATALYTIC ACTIVITY, NICKEL COMPLEX, CHLOROMETHANE, COPPER COMPLEX, COBALT COMPLEX, EPOXIDATION REACTION
