ABSTRACT
Diiron(IV)-oxo species are proposed to effect the cleavage of strong C-H bonds by nonheme diiron enzymes such as soluble methane monooxygenase (sMMO) and fatty acid desaturases. However, synthetic mimics of such diiron(IV) oxidants are rare. Herein we report the reaction of (TPA*)FeII (1) (TPA*=tris(3,5-dimethyl-4-methoxypyridyl-2-methyl)amine) in CH3 CN with 4â
equiv CAN and 200â
equiv HClO4 at 20 °C to form a complex with an [FeIV2 (µ-O)2 ]4+ core. CAN and HClO4 play essential roles in this unprecedented transformation, in which the comproportionation of FeIII -O-CeIV and FeIV =O/Ce4+ species is proposed to be involved in the assembly of the [FeIV2 (µ-O)2 ]4+ core.
