Electrochemical cross-coupling between functionalized aryl halides and 2-chloropyrimidine or 2-chloropyrazine catalyzed by nickel 2,2′-bipyridine complex

2-Arylpyrimidines and 2-arylpyrazines have been obtained in good to high yields from 2-chloropyrimidine and 2-chloropyrazine and various functionalized aryl halides by electroreduction using an iron rod as the anode and a catalytic amount of nickel–bipyridine complex in a mixture of DMF and pyridine as solvent.
