A New Phase-Transfer Porphyrin Catalyst for the Olefin Epoxidation

Abstract
A new type of amphiphilic porphyrin has been synthesized and its manganese(III) complex has been used as a catalyst for the epoxidation of olefin. Catalytic oxygenation in a two-phase (CH2Cl2/H2O) system has been undertaken in the absence of a phase-transfer reagent, such as benzyldimethyltetradecylammonium chloride.
