Oxidative polymerization of 2,6-dimethylphenol in water using bis-triazacyclononane copper catalyst



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.
