to form bis(1-aryliminomethylenylnaphthalen-2-oxy)nickel complexes. All resultant compounds were structurally characterized by elemental analyses, IR and H NMR, and the structures of the formed complexes were elucidated by X-ray crystal structure analysis. The complexes show high catalytic activities for the vinyl polymerization of norbornene in the presence of methylaluminoxane. The catalytic activity
合成的1-芳基亚甲基亚甲基萘-2-醇衍生物与氯化镍反应形成双(1-芳基亚甲基亚甲基萘-2-氧基)镍配合物。通过元素分析,IR和1 H NMR对所有所得化合物的结构进行表征,并通过X射线晶体结构分析阐明形成的配合物的结构。在甲基铝氧烷的存在下,该配合物对降冰片烯的乙烯基聚合显示出高催化活性。气相色谱法通过监测降冰片烯的转化来跟踪催化活性的变化。
