摘　　要：N-杂环卡宾铂配合物作为催化剂广泛应用于诸多有机催化反应,表现出优良的催化性能及稳定的物理、化学性质,在一定程度上解决了传统催化剂使用过程中遇到的稳定性难题,是有机金属催化化学的研究热点之一。本文介绍了近年来N-杂环卡宾铂配合物的合成及其作为催化剂在不饱和化合物(烯烃、炔烃和酮等)硅氢加成反应、烯炔环异构化反应、烯烃氢胺化、烯烃硼化反应和炔烃水化反应等有机反应中的应用研究新成果和进展,分析了N-杂环卡宾铂配合物作为催化剂的催化机理和存在的不足,并对N-杂环卡宾铂配合物作为催化剂的应用前景进行了展望。N-heterocyclic carbenes（NHC） have long been recognized as important ligands in organometallic chemistry,and NHC can form stable metal-carbon bonds w ith metals because of their stong σ-donating ability that provides the possibility to develop platinum NHC complexes as catalysts. N-heterocyclic carbene-platinum（Pt-NHC） complexes have been widely applied as catalysts in numerous catalytic organic reactions,in which the Pt-NHC system show s excellent catalytic performance and features w ith stable physical and chemical properties.On the other hand, the Pt-NHC complexes could be easily modified w ith different functional groups by modification of the stereo-effect and the corresponding electronic properties. In past years,it provides an effective method to solve the problem encountered in the process of using the traditional catalyst,and has become one of the hot topics in the organometallic chemistry and catalytic chemistry. In this manuscript,w e summarize the recent progress in the synthesis of Pt-NHC complexes and their application in the catalytic organic transformations, including hydrosilylation of olefins/alkynes and ketones, isomerization reaction,hydroamination of unactivated olefins, borylation reactions of olefins, and hydration reaction of alkynes.Furthermore,the catalytic mechanism of all these reactions has been discussed. At last,the deficiencies as w ellas the perspective of Pt-NHC complexes have been also highlighted.
