Mimicking reactive high-valent diiron-μ2-oxo intermediates of nonheme enzymes by an iron tetracarbene complex

The first diiron(iii,iv)-mu(2)-oxo tetracarbene complex is isolated and characterized by SC-XRD, UV/Vis, EPR, Evans' NMR and elemental analysis. CV indicates the presence of a transient high-valent diiron(iv)-mu(2)-oxo species. Its formation and decay is investigated via UV/Vis kinetics and NMR.
