The dissolution of a stainless steel anode provides catalytic nickel species which enable the efficient synthesis of ketones by electrolysis of organic halides in DMF in the presence of bipyridine and carbon monoxide.

reduction of a 2,2′-bipyridine-nickel complex, in the presence of carbon dioxide in N-methylpyrrolidone or dimethylformamide as solvent gives the corresponding nickel(0) complex associated with two molecules of CO. Oxidative addition of an alkyl halide to this complex, followed by an internal CO shift and reductive elimination, leads to the formation of a symmetrical ketone in high yield along with nickel(II)
