摘　　要：4个基于2-吡唑啉-9-芳基邻菲咯啉(L1-L4)镍配合物[NiCl_2L](1-4)被开发用于芳基卤化物和格氏试剂偶联反应的研究,表现出良好的催化活性.对配合物(4)的结构进行了x-单晶衍射表征,分析发现中心金属镍为五配位的四方锥构型利于C—C偶联反应.讨论了配体空间位阻及反应条件对该偶联反应活性的影响,发现邻菲咯啉的9位位阻对催化活性影响更明显.Four nickel complexes [NiCl2L]（1-4） supported by a tridentate pyrazolyl-based phenanthroline ligand（L1-L4）have been developed for C—C coupling reactions. The nickel complexes exhibited moderate catalytic activities for C—C coupling reactions of various aryl halides with Grignard reagent. Single-crystal X-ray diffraction analysis of the complex [NiCl2L4]（4） reveal a distorted trigonal bipyramidal geometry at the Ni（II） center,which creates a reaction channel to facilitate C—C coupling reactions.
