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

Chem Commun (Camb). 2021 Jul 6;57(54):6644-6647. doi: 10.1039/d1cc02027g.

Abstract

The first diiron(iii,iv)-μ2-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)-μ2-oxo species. Its formation and decay is investigated via UV/Vis kinetics and NMR.
