Özet
Recent studies have shown that non-heme iron complexes [Fe(LN4)X2], where LN4 stands for a tetradentate nitrogen based aminopyridine ligand (LN4 = Pytacn, mcp or mep, Pytacn = 1-(2-pyridylmethyl)-4,7-dimethyl-1,4,7-triazacyclononane, mcp = N,N′-dimethyl-N,N′-bis(2-pyridylmethyl)cyclohexane-trans-1,2-diamine, mep = N,N′-dimethyl-N,N′-bis(2-pyridylmethyl)ethylendiamine), and X are monodentate ligands (X = Cl, CH3CN, CF3SO3–, or H2O), catalyze the oxidation of water using cerium(IV) ammonium nitrate (CAN) as oxidant. Spectroscopic monitoring of catalytic water oxidation with [Fe(CF3SO3)2(Pytacn)] established [FeIV(O)(OH2)(Pytacn)]2+ as an intermediate along the catalytic pathway, raising the question if these high valent species could be directly responsible for the O–O bond formation event. Herein, this question is addressed by a computational analysis of the thermodynamic and kinetic …
