N-杂环卡宾金属配合物具有良好的化学稳定性和催化活性,一直是有机化学研究领域中的热点.咪唑盐作为N-杂环卡宾的前体,其制备容易,结构多样的特点为构建拓扑结构的N-杂环卡宾金属配合物提供了基础.主要针对近年来由环状多咪唑盐、非环状多咪唑盐为配体与金属进行组装,或以咪唑盐与P/N配体与金属共同组装,或经过异腈分布合成法形成的具有特殊柱状、笼状、环状、“分子方”和“分子矩形”等结构的多N-杂环卡宾金属配合物的合成,结构及物理化学性质进行归纳总结,并对其研究前景进行了展望.
N-heterocyclic carbene metal complexes have good chemical stability and catalytic activity, and have always been the hot topics in the field of organic chemistry.Immidazole salts, as precursors of N-heterocyclic carbenes, are easy to prepare and diverse in structure, Topological structure of the N-heterocyclic carbene metal complexes provide the basis for the main in recent years by the cyclic polyimidazolium salt, acyclic polyimidazolium salt ligand for the assembly with the metal, or with imidazole salt and P / N ligand Heterocyclic polycarboside metal complexes with special structures such as column, cage, ring, “molecular square” and “molecular rectangular” formed by co-assembly with metal or by isonitrile synthesis Synthesis, structure and physical and chemical properties summarized, and its research prospects are prospected.
