Abstract

The iron(II) complex of the macrocyclic ligand 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraaza-cyclotetradecane was synthesized and characterized and used as a mimetic peroxidase in the catalytic oxidation of phenol with H2O2. The mechanism and a kinetic model of the catalytic oxidation are described. The results show: the catalyst as a peroxidase mimic exhibited strong catalytic activity; the main reaction products detected by high-pressure liquid chromatography (HPLC) were catechol, hydroquinone, p-benzoquinone, maleic acid and oxalic acid; the catalytic oxidation of phenol accords with the enzyme mechanism.
