Oxidatively Induced Carbon−Halogen Bond-Forming Reactions at Nickel

This communication describes the first reported example of carbon−halogen bond formation from an isolable nickel aryl halide precursor. In addition, oxidatively induced Ar−Br bond-forming reactions from the nickel(II) complex NiII(phpy)(Br)(pic) (phpy = 2-phenylpyridine; pic = 2-picoline) are demons...

Summary:This communication describes the first reported example of carbon−halogen bond formation from an isolable nickel aryl halide precursor. In addition, oxidatively induced Ar−Br bond-forming reactions from the nickel(II) complex NiII(phpy)(Br)(pic) (phpy = 2-phenylpyridine; pic = 2-picoline) are demonstrated using CuBr2, Br2, ceric ammonium nitrate, and ferrocenium as oxidants. On the basis of several pieces of evidence, the intermediacy of Ni(III) species is proposed in these transformations.
