| 摘 要： | 利用1-苯基-3-(2,4,6-三甲基苯基)丙烯酮和2-肼-9-芳基邻菲咯啉的缩合反应合成了一系列2-N-(3-笨基-5(2,4,6-三甲基笨基)吡唑啉)]-9-芳基邻菲咯啉类配体(L_1-L_4),分别与NiCl_2反应得到了相应的配合物NiCl_2](1-4), 对配体和配合物进行了表征, 并用X-单晶衍射分析了配合物4的晶体结构, 表明Ni中心为五配位的四方锥构型. 化合物l-4在MAO存在下对乙烯齐聚表现出良好的催化活性. 在1 Mpa 乙烯压力下, 化合物4的催化活性最好, 高达2.52×10~5g mol~(-1) h~(-1). 讨论了配体空间位阻及反应条件对乙烯齐聚活性的影响, 发现邻菲咯啉的9-位位阻对催化活性影响更明显.

| Abstract: | Four new ligands,2-N-(3-phenyl-5-(2,4,6-trimethylphenyl)-pyrazolinyl)]-9-aryl-1,10-phenanthroline(L1-L4),have been synthesized by the condensation of 1-phenyl-3-(2,4,6-trimethylphenyl)-propenone and 2-hydrazine-9-aryl-1,10-phenanthroline,which reacted with NiCl2 to afford the corresponding nickel complexes 1-4.All ligands and complexes were fully characterized.The structure of complex 4 was determined by X-ray single crystal diffraction analysis,which revealed that the nickel center is five-coordinated by ... |
