摘　　要：在过渡金属有机化学中,含过渡金属-主族元素(C,N,P)双键的卡宾配合物化学具有重要地位.它不仅对人们理解过渡金属和主族元素的成键理论很重要,而且这类配合物具有一些很好的、以及特征性的反应和催化性能.在过去的30年中,人们在含稀土金属-主族元素(C,N,P)单键的稀土金属烷基、胺基配合物以及膦基配合物化学研究上取得了很好的进展.稀土卡宾配合物化学是相关研究工作者接下来需要和渴望开拓的一个重要领域.人们在这一方面进行了积极的探索,合成得到了一些稀土桥联卡宾配合物和稀土卡宾配合物的模拟物.虽然它们离稀土金属-主族元素双键的稀土末端卡宾配合物有差距,但可以为稀土末端卡宾配合物的研究提供一些线索.本论文论述了这方面的研究成果,以及最近在稀土末端氮卡宾配合物上的一个突破.The transition metal complexes, which contain M=E （E = C, N, P） double bond, are very important. Not only the understanding of the nature of transition metal-main group element double bond is of fundamental concem, but also these complexes have some excellent and unique reactivities. Rare-earth metal alkyl, amide and phosphide complexes have been extensively studied during the last three decades. However, the chemistry of rare-earth metal alkylidene, imido and phosphinidene complexes remain challenging. The efforts in this field led to some bridged alkylidene, imido and phosphinidene complexes, and phosphorus-stabilized ＂pincer＂ type alkylidene complexes. Although these reported complexes are different from their ＂terminal＂ cousins, which contain M=E （E = C, N, P） double bond, they shed light on the exploration to rare-earth metal terminal alkylidene, imido and phosphinidene complexes. This paper covers the synthesis, structures and reactivities of the bridged alkylidene, imido and phosphinidene complexes, phosphorus-stabilized ＂pincer＂ type alkylidene complexes as well as a recent breakthrough in the rare-earth metal terminal imido complexes.
