Electrosynthesis of functionalized 2-arylpyridines from functionalized aryl and pyridine halides catalyzed by nickel bromide 2,2′-bipyridine complex

2-Arylpyridines substituted on aryl and/or on pyridine nuclei can be obtained in good to high yields in one step by electroreduction of mixtures of the corresponding aryl and pyridyl halides using the sacrificial iron anode process and a nickel 2,2′-bipyridine complex catalyst in DMF as solvent.
