| Abstract;Substarate oxidation using high-valent iron or manganese oxo specie has been extensively studied as a model of P450 by using peroxides to produce the high-valent iron or manganese oxo species. We report herein substarate oxidation by the high-valent manganese oxo species ((P)Mn(IV)(=O+) generated by the electron transfer oxidation with Ru(bpy)33+ (bpy=2,2'-bipyridine) as an one-electron oxidant, in which water is used as the oxygen source. Addition of Ru(bpy)33+ to an MeCN solution of olefins (styrene, cyclohexene) containing water in the presence of a catalytic amount of a series of (P)Mn affords epoxides, diols and aldehydes efficiently. Ethylbenzene is also oxidized to 1-methylbenzylalchol using (P)Mn (P=TMP, TDCPP and TPFPP), whereas adamantane is oxidized to 1-adamantanol only by using (TDCPP)Mn. These products are detected by GC-MS and 1H-NMR. (author abst.) |
