Abstract
Laccaseβcatalyzed oxidative polymerization of phenol and its derivatives has been performed in aqueous organic solvents at room temperature in air. Laccase derived from Pycnoporus coccineus efficiently induced the polymerization to produce polyphenols consisting of a mixture of phenylene and oxyphenylene units. The unit ratio of the polymer could be precisely controlled by selection of the solvent and the monomer substituent.

Rhus vernificera laccase-catalyzed oxidation of phenolic compounds, i.e., (+)-catechin, (-)-epicatechin and catechol, was carried out in selected organic solvents to search for the favorable reaction medium. The investigation on reaction parameters showed that optimal laccase activity was obtained i
This paper presents an overview on recent developments of oxidative polymerizations of phenols, particularly focusing on the coupling selectivity. In 1959, Hay et al. discovered an oxidative polymerization of 2,6-dimethylphenol catalyzed by a copper/amine complex to produce poly(2,6-dimethyl-1,4-phe
