Structural and Spectroscopic Characterization of (μ-Hydroxo or μ-Oxo)(μ-peroxo)diiron(III) Complexes: Models for Peroxo Intermediates of Non-Heme Diiron Proteins
摘要:
(mu-Hydroxo or oxo)(mu-1,2-peroxo)diiron(III) complexes having a tetradentate tripodal ligand (L) containing a carboxylate sidearm [Fe2(mu-OH or mu-O)(mu-O2)(L)2]n+ were synthesized as models for peroxo-intermediates of non-heme diiron proteins and characterized by various physicochemical measurements including X-ray analysis, which provide fundamental structural and spectroscopic insights into the peroxodiiron(III) complexes.
A mononuclear peracetatoiron(III) complex [Fe(6Me2-BPP)(CH3C(O)O2)]+ (2) with a tripodal ligand (6Me2-BPP) was prepared in the reaction of an iron(II) complex [Fe(6Me2-BPP)(H2O)]+ (1) with peracetic acid. 2 is the first example of a structurally and spectroscopically well-defined non-heme type peracetatoiron(III) complex and has modest oxidation ability toward triphenyl phosphine, some olefins, and the tertiary C–H bond of adamantane.
