Abstract
Abstract 6-Bromopicoline can be reductively homocoupled to provide 6,6′-dimethyl-2,2′-bipyridine in high yield either by an Ni·bpy catalysed electrosynthesis or by a catalytic modification of the Ullmann synthesis employing Pd(OAc) 2 . Either procedure is operationally simple and represents a considerable improvement over most known syntheses of this important disubstituted bipyridine.
