摘　　要：采用多步偶联的方式合成了基于氧杂蒽骨架的配体及相应的镍金属配合物,通过核磁共振谱、碳谱及元素分析对配合物及其配体进行结构表征分析,利用单晶衍射阐述了配合物的立体结构。采用该配合物与含铝助剂配合使用能有效催化乙烯寡聚,活性最高可达到5×10^(6)g/(mol·h),产品组成以C_(4)为主。The ligands based on xanthene framework and the corresponding nickel metal complexes were synthesized by multi-step coupling method.The structures of the complexes and their ligands were characterized by nuclear magnetic resonance(NMR),carbon spectroscopy and elemental analysis.The stereoscopic structure of the complexes was more clearly described by single crystal diffraction.The results showed that the complex can effectively catalyze the oligomerization of ethylene with the highest activity of 5000kg/(mol·h)and the main component of the product was C_(4).
