Hybrid zinc(Ⅱ) and iron(Ⅲ) porphyrin dimer,linked with a short flexible hydrocarbon chain(Fig.1),has been synthesized and characterized by EA,IR,¹H-NMR,XPS,and EPR spectroscopy.As a new model system of cytochrome P450,hybrid zinc(Ⅱ) and iron(Ⅲ) porphyrin dimer like iron(Ⅲ) porphyrin effectively catalyze hydroxylation of cyclohexane with molecular oxygen under mild conditions and catalytic activities of dimer are higher than those of iron(Ⅲ) porphyrin.Factors affecting catalytic activities are discussed from the point of view of partial intramolecular redox.
