Many enzymes containing mononuclear nonheme iron active sites are involved in dioxygen activation and the oxidation of organic substrates in biological systems.In the catalytic mechanisms of these enzymes, metal-peroxo and/or high-valent metal-oxo species are implicated as the key reactive intermediates in the chemistry of bleomycin, superoxide reductase, and α-ketoglutarate dioxygenase. With synthetic model complexes, a number of peroxoiron(III) and oxoiron(IV) species have been well characterized with various spectroscopic techniques and the reactivities of these complexes were investigated in a number of oxidation reactions.we report that axial ligand substitution of a mononuclear nonheme oxoiron(IV) complex bearing 13-membered macrocycle ligand, [FeIV(O)(TATM)(X)] + (TATM = 1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclotridecane, X = CH3CO2, N3, SCN), leads to the formation of FeIV=O species at low temperature and present the observation of Fe=O vibrations by resonance Raman spectroscopy.
