| Abstract: The selective oxidation of cyclohcxane to cyclohexanol and cyclohcxanonc was realized in the model system of cytochrome P-450 consisting of mctalloporphyrins, molecular oxygen, ascorbic acid and substrate. The products, cyclohcxanol, and cyclohcxanonc were found to be sensitive to the peripheral substitution pattern of the mctalloporphyrins. The effects of the central metal ion, the axial ligand, the ratio of substrate to catalyst, and pH on the reaction were investigated and finally the reaction mechanism of the activation of molecular oxygen by the mctalloporphyrins was proposed. |
