A series of 2-benzoimidazol-8-ethoxyquinolines (L1–L6) and the nickel dihalides thereof (C1–C12) were synthesized and characterized by elemental analysis and infrared spectroscopy. The molecular structures of representative complexes were determined by single crystal X-ray diffraction which revealed a distorted pyramidal geometry at nickel. All complexes, when activated with Et2AlCl, showed high activities towards ethylene oligomerization and enhanced thermodynamic stability.
本研究合成了一系列 2-苯并咪唑-8-乙氧基喹啉(L1-L6)及其二卤化镍(C1-C12),并通过元素分析和红外光谱进行了表征。通过单晶 X 射线衍射确定了代表性配合物的分子结构,发现镍的几何形状为扭曲的金字塔形。所有配合物在用 Et2AlCl 活化后,都显示出较高的乙烯低聚活性和较强的热力学稳定性。
