Ionic manganese porphyrins with s-containing counter anions: Mimicking cytochrome P450 activity for alkene epoxidation
The ionic manganese porphyrins, composed of trimethylbenzylammonium cations and S-containing anions, were designed to mimic cytochrome P450. S-containing anions could function as the stoichiometric axial ligands and counterions dually. Such ionic catalysts showed good catalytic performance in alkene epoxidation as compared with their neutral counterparts, in terms of activity, epoxide selectivity, and recyclability.
