Water soluble 1,4,7‐triazacyclononane derivatives were synthesized as the model of the tyrosinase binuclear active site and their copper (II) complexes have been employed as a catalyst for the oxidative polymerization of 2,6‐dimethylphenol using water as the solvent. With this enzyme mimic catalytic system, the polymer, poly(2,6‐dimethyl‐1,4‐phenylene oxide), was successfully obtained from the polymerization with suppression of the formation of the quinone by‐product, 4‐(3,5‐dimethyl‐4‐oxo‐2,5‐cyclohexadienylidene)‐2,6‐dimethyl‐2,5‐cyclohexadien‐one, during the polymerization process. © 2011 Wiley Periodicals, Inc.
