摘要/Abstract

导向基团辅助的C-H活化是选择性活化分子中特定位置C-H键的重要措施，也是近年来有机化学研究的热点.羧酸作为一种高效导向基团具有价廉、低毒、容易修饰和作为无痕导向的优点而受到广大化学工作者的关注.按照羧基导向偶联方式的不同进行分类，综述了近年来过渡金属催化羧基导向C-H官能团化研究进展，并对代表性性反应机理做了简要说明.同时，对这一领域存在的问题和未来可能的发展方向进行了展望.

The C-H activation assisted by directing groups is an important measure for selective C-H activation at specific positions, and it is also one of the hot spots in the research field of organic chemistry. As an efficient directing group, carboxylic acid has the advantages of low cost, low toxicity, easy modification and using as traceless directing groups. Recent development on C-H functionalization directed by carboxyl group according to different coupling modes is summarized, and the representative reaction mechanism is briefly described. Existing problems with a brief outlook in this field are also presented.
Key words: catalysis, C-H activation, carboxylic acid, traceless directing group, reaction mechanism
