Syntheses of metalloporphyrin compounds 3 were accomplished to mimic the natural cytochrome P-450. The micelle made of surfactant, lauryl trimethyl ammonium bromide, and long chain alkoxyl phenyl porphyrin is employed as a biomimetic enzyme and the results of epoxidation of styrene shown that the metalloporphyrin appended with a long hydrocarbon chain does have superior catalytic efficiency over the simple 5,10,15,20-tetratolyl porphyrin. The present experimental findings demonstrate evidently that the hydrophobic microenvironment provided by the aggregate long hydrocarbon chain in the micelle do play an important role in the epoxidation of styrene.
