trans-Haloarylbis(triphenylphosphine)nickel(II), a type of air- and moisture-stable Ni(II)-(sigma-aryl) complex, was examined as catalyst precursor in the C-N coupling reaction. This type of Ni(II) pre-catalyst, associated with N-heterocyclic carbene ligands, is found to easily produce the catalytically active Ni(0) species in situ without the aid of external reductants and allows for the efficient amination of aryl chlorides with secondary cyclic amines and anilines under mild conditions.
反式卤代芳基双（三苯基膦）镍（II）是一种对空气和湿气稳定的Ni（II）-（σ-芳基）配合物，被作为C-N偶联反应中的催化剂前体进行了研究。这种与N-杂环卡宾配体相关的Ni（II）预催化剂，被发现能够在无需外部还原剂的情况下，原位轻松生成催化活性的Ni（0）物种，并能在温和条件下实现芳基氯与仲环胺和苯胺的高效胺化反应。
