Abstract

AbstractMononuclear amino triphenolate iron(III) complexes have been synthesized and characterized (UV/Vis spectroscopy, cyclic voltammetry, ESI‐MS, 1H 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).
