A process for producing unsaturated nitrogen containing compounds such as enamides, enamines and aryl amines/amides is disclosed. A vinyl halide or aryl halide is reacted with an -NH- containing compound in the presence of a catalytic amount of a catalyst precursor composition comprising zero-valent nickel and an organophosphine ligand. One step coupling of vinyl halides and aryl halides with -NH- containing compounds is made possible by practice of this invention.
Enamides and enimides were prepared stereospecifically from vinyl bromides by direct vinylic substitution in the presence of copper salt in aprotic polar solvents.
