The consumable anode process permits the electrochemicalarylation of activatedolefins from functionalized aryl halides when cobalt halide is used as catalyst, either associated with bipyridine and pyridine as ligands in DMF as solvent, or with only pyridine in acetonitrile as solvent.
Nickel-catalyzed electrochemical conjugate additions of substituted aryl bromides to activatedolefins under recently optimized reaction conditions are reported. Good to high yields were obtained, whatever the nature of substituents in the meta- and para-positions of the benzene ring. In the ortho-substituted series, yields were good with electron-donating substituents, but low with electron-withdrawing
