Abstract

Abstract Low temperature oxidations of selected higher order cyanocuprates composed of one or two heteroaromatic ligands can be oxidatively coupled in an inter-or intramolecular fashion to afford unsymmetrical biaryls. Non-heteroaromatic systems have also been studied in related intramolecular processes.
