O-O bond cleavage by electrochemical reduction of a side-on peroxo dicopper model of hemocyanin.

Abstract

The redox properties of the μ-η2:η2 peroxo complex [Cu2(H6M4h)(O2)]2+ were elucidated. This study constitutes the first full electrochemical and spectroelectrochemical characterization of a side-on peroxo Cu2:O2 bioinorganic model complex. The peroxo complex is irreversibly reduced in a two- electron process localized on the peroxo ligand triggering the cleavage of the O-O bond
Les propriétés redox du complexe peroxo μ-η2:η2 [Cu2(H6M4h)(O2)]2+, modèle de l’hémocyanine, ont été élucidées par des études électrochimiques et spectroélectrochimiques. La réduction du complexe peroxo est irréversible et s’effectue selon un processus à deux électrons localisé sur le ligand peroxyde, déclenchant la rupture de la liaison O-O.
