Mn(III)-porphyrin에 의한 Styrene 유도체의 산화반응 메카니즘 연구

Kinetic Investigation of Styrene Derivatives Oxidation Mechanism by Mn(III)-porphyrin

The catalytic activities of several metalloporphyrin, wherein the porphyrins are TPP(5,lO,l5,20-Tetraphenyl-21H,23H-porphyrin) and (p-X)TPP (X=CH3O, CH3, F, Cl), are reported for the oxidation of styrene and it s derivatives. The electronic effects of substrates and porphyrins on the catalytic activity of metalloporphyrin containing the transition metal ion such as Mn(III) was discussed. Investigating the correlation between the Michaelis-Menten s rate parameters and the substituent constants, we are going to analyze the influences on the changes of catalytic activity or rate determining step during the processes of the formation and the dissociation of the M-oxo-olefin.
