摘要：

The perhalogenated porphyrin ruthenium complex (TFPPCl(8))Ru(CO) (TFPPCl(8) = octachlorotetrakis( pentafluorophenyl) porphyrin) catalyzes aerobic oxidation of olefins at room temperature. Cyclohexene is oxidized primarily at the allylic position, and styrene primarily to benzaldehyde, indicating a radical autoxidation mechanism. Reactions are enhanced by visible light. Reaction with m-chloroperbenzoic acid converts the ruthenium complex to (TFPPCl(8))Ru(O)(2), but such oxo complexes do not appear to participate in catalytic aerobic oxidation.
