Imidazole Complexes Catalyze the Oxidative Polymerization of 2,6-Dimethylphenol with Dioxygen

Patrick J. Baesjou , Ger Challa Willem L. Driessen and Jan Reedijk [Pg.444]

The oxidative dehydrogenation polymerization of 2,6-dialkylphenoles has been known for many years to be catalyzed by copper amine complexes [1] see figure for 2,6-dimethylphenol oxidation. The mechanism of action of this industrially very important reaction has been studied for some time by several groups. [Pg.444]

The amount of DPQ, the undesired side product, needs to be reduced as far as possible. [Pg.444]

The resemblance with certain bioinorganic dehydrogenases is of great interest and knowledge in one area is likely to benefit also the other area. [Pg.444]

The reoxidation step appears to involve a very reactive copper-dioxygen intermediate, which recentfy has been studied spectroscopically and kmeticaUy for certain biomimetic systems. [Pg.444]
