Dioxygen–copper reactivity at trinuclear centers: formation of hexanuclear and mixed-valent adducts
Abstract
New copper(I) complexes [CuI3(mesO–)]2+ (3) and [CuI3- (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.
