摘要

Abstract Oxidation of phenols by molecular oxygen in the presence of the μ-oxo cupric catalyst Cu 4 Cl 4 O 2 (CH 3-CN) 3 (A), can be selectively directed to give either oxidative coupling or para-hydroxylation (p-quinols or p-quinones) products by the choice of the (A)/(phenol) ratio. The mechanism is discussed and a-OH ligand transfer from Cu II to the phenolic para position is proposed.
