【摘要】 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.更多还原

【Abstract】 Owing to the excellent chemical stability and catalytic activity, N-heterocyclic carbene(NHC) complexes have always been the hotspot in the field of organic chemistry. Imidazolium salts are the precursors of NHCs, and their easy preparation and structure diversity properties make them useful for the generation of NHC complexes with topology structures. In this paper, the recent progress of synthesis, structure and physicochemical properties of NHC complexes with cylindrical, cage-like, macrocyclic, square and rectangular molecular structures which are synthesized by poly-imidazolium salts is summarized and reviewed.更多还原
