Inter- and Intramolecular Biaryl Couplings Via Cyanocuprate Intermediates

Article abstract of DOI:10.1016/S0040-4039(00)75970-3

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.
