Studies on the Self-Oxidation of Metal loporphyrins

Abstract

Abstract: We synthesized 9 kinds of metalloporphyrins and studied systematically the kinetic properties of their self-oxidation during the biomimetic oxidation of hydrocarbons. It has been proved that the kinetic properties of the self-oxidation of the metalloporphyrins depend on the metal ions bonded with the porphyrins. The reaction is second order for ironporphyrins or chro-moporphyrins, and first order for manganoporphyrins. It is shown from the results that the rateof the reaction is much related to the structure of the porphyrins--the substituents on the por-phyrin ring and the axial ligandsr the properties of the oxidants and the reaction mediums, and is abated by adding some neutral organic ligands to the reaction system.

Key words: Metalloporphyrin, Oxidation, Kinetics
