过渡金属催化的偶联反应是有机合成中碳-碳键形成的重要方法,也是当前有机化学研究领域的热点之一.直接以过渡金属盐或配合物作催化剂有价格昂贵、不易回收、痕量残留、污染产物和环境等弊端.在环境问题倍受关注的今天,寻找绿色的物质转化途径,开发可循环使用的负载型高效催化剂已成为化学家解决上述问题的重要途径之一.按照载体分类,综述了负载型催化剂在碳-碳键偶联反应中的研究进展.
Transition-metal-catalyzed coupling reactions are important methods for the formation of carbon-carbon bonds in organic synthesis and are also one of the current hot topics in the field of organic chemistry.Direct transition metal salts or complexes as catalysts are expensive and difficult to recover, Residues, pollution products and the environment, etc .. In today’s environmental issues have drawn much attention today, looking for a green material conversion pathway, the development of reusable, supported and efficient catalysts has become an important way for chemists to solve the above problems.According to the carrier classification The research progress of the supported catalysts in the carbon-carbon bond coupling reaction is reviewed.
