摘要：

The title compound (1) oxidizes 2,6-di-tert-butylphenol (2), 2, 6-di-tert-butyl-4-methylphenol (3), 2,6-di-tert-butyl-4-(diphenylmethyl)phenol (4), and beta-naphthol (5), to quinones in good yield under mild conditions in acetonitrile. For unsubstituted phenols the reaction takes place in two ways, phenol (6) is oxidized to quinhydrone (7), while the oxidation products of the phenols, alpha-naphthol, catechol and 2,4-dihydroxyl-naphthol were only polymers.
