Graphical Abstract

Der Donor macht den Unterschied: Der Disauerstoff-Ligand des einkernigen η1-Superoxo-Kupfer(II)-Komplexes 1 wird durch Wasserstoffatomdonoren aktiviert. Der resultierende Einschub eines O-Atoms aus der O2-Gruppe in die N-gebundene Methylgruppe des Chelatliganden führt zu dem Kupfer(II)-alkoxid 2. Ohne Zusatz des Donors ist die Superoxospezies 1 nicht in der Lage, die beobachtete Hydroxylierung einzugehen.
