Dioxygen–copper reactivity at trinuclear centers: formation of hexanuclear and mixed-valent adducts

Abstract

New copper(I) complexes [Cu^I₃(mesO^–)]²⁺ (3) and [Cu^I₃- (mesOH)]³⁺ (4) have been generated from a phenol-containing trinucleating ligand, mesOH; reactions with O₂ reflect the unsymmetrical ligand environment, and lead to peroxo and/or hydroperoxo cluster complexes, including those with mixed-valent copper ion centers.
