A bi-copper(I)/bi-copper(II) redox cycle in the co-ordination and activation of dioxygen by a bi-copper(I) complex of a macrocyclic ligand
Abstract
The rapid absorption of one mol of dioxygen by one mol of a bi-CuI macrocyclic complex in MeCN is followed by a slower anaerobic oxidative dehydrogenation of the ligand by the bound dioxygen to regenerate the CuI centres so that the cycle may be repeated, at least once again although more slowly.
