Mononuclear Iron(III) Complexes as Functional Models of Catechol Oxidases and Catalases

Abstract

Abstract Mononuclear amino triphenolate iron(III) complexes have been synthesized and characterized (UV/Vis spectroscopy, cyclic voltammetry, ESI‐MS, 1 H NMR spectroscopy, X‐ray diffraction). These complexes act as biomimetic catalysts promoting the aerobic auto‐oxidation of 3,5‐di‐ tert ‐butylcatechol to the corresponding o ‐benzoquinone at room temperature and displaying catalase activity for the hydrogen peroxide dismutation with remarkable activity (TON up to 4000).
