Aromatic hydroxylation in a new tyrosinase model system and formation of a novel bis(µ-hydroxo)dicopper(<scp>II</scp>) complex due to an unprecedented ligand coupling reaction

Abstract

A new binucleating nitrogen-donor ligand exhibits tyrosinase-like activity by bringing about aromatic hydroxylation mediated by copper; the phenoxy- and hydroxyl-bridged copper(II) complex 1 and a novel dihydroxy-bridged copper(II) complex 2 are structurally characterized.
