Oxidation mechanism of phenols by copper(ii)–halide complexes

Abstract

The mechanism of oxidation of phenols by tetrahedral copper(II)–halide complexes was investigated to demonstrate that phenols with an electron-withdrawing substituent are oxidized via a proton-transfer/electron-transfer (PTET) mechanism, whereas phenols with an electron-donating substituent involve a concerted proton/electron transfer (CPET) mechanism. The importance of the tetrahedral geometry of the metal centre as well as the effects of the halide ligands of the substrates were explored.
