Propylene Epoxidation Catalyzed by a Biomimetic System of Cytochrome P450 Supported Metalloporphyrin on SiO2
Abstract:
SiO2 supports chemically modified by amine, imidazole were prepared and used to support Mn(TPP)Cl, Mn(TDCPP)Cl for constructing the biomimetic systems of cytochrome P-450 with the single oxygen donor (NaClO) as the terminal oxidant. With such catalytic systems, the propylene could be epoxidized under mild conditions in the aqueous solution of sodium hypochlorite. This fair catalytic behavior compared with that of the unsupported Mn(TPP)Cl was ascribed to the axial ligation of organofunctional group on the SiO2 surface to the central metal of the metalloporphyrins, and the site isolation of active centers which would prevent the formation of μ-oxo-dimers.
