A nickel-catalyzed conjunctive cross-coupling of simple alkenyl amides with aryl iodides and aryl boronic esters delivers the desired 1,2-diarylated products with excellent regiocontrol. The reaction is enabled by an electron-deficient olefin (EDO) ligand. Under optimized conditions, a wide range of amides derived from 3-butenoic acid, 4-pentenoic acid, and allyl amines are compatible substrates.
