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.
                                    本交流描述了第一个报道的可分离的芳基
镍卤化物前体形成碳-卤素键的例子。此外,使用CuBr 2,Br证明了
镍(II)络合物Ni II(phpy)(Br)(pic)(phpy = 
2-苯基吡啶; pic = 2-picoline)的氧化诱导Ar-Br键形成反应。2,
硝酸铈铵和
二茂铁作为氧化剂。根据一些证据,在这些转化中提出了Ni(III)物种的中间产物。
