Recent Advances in Photocatalytic Carboxylation with CO_(2)viaσ-Bond Cleavage

二氧化碳(CO_(2))作为温室气体的主要成分之一,也是目前最丰富的碳源之一.CO_(2)常常作为C1合成子,通过构建C—C键合成羧酸类化合物.过渡金属催化的发展为CO_(2)的转化和利用提供了有力的工具.为了实现“双碳”战略目标,结合有机化学领域的研究热点,发展绿色、可持续的CO_(2)转化和利用技术具有重要意义.近年来,光催化合成技术的发展为CO_(2)的转化和利用提供了新的契机.系统阐述了光催化下CO_(2)参与的C—H、C—O、C—N及C—X键的断键及羧基化反应.

Carbon dioxide(CO_(2)),as the main components of greenhouse gases,is one of the most abundant carbon sources at present.In organic chemistry,CO_(2)is often used as C1 synthon to synthesize carboxylic acids by constructing C—C bond.Transition metal catalysis has developed as a powerful tool for the conversion and utilization of CO_(2).In order to achieve the strategic goal of“double carbon”,it is of great significance to develop green and sustainable CO_(2)conversion and utilization technology combined with contemporary hot topics in the field of organic chemistry.In recent years,the development of photocatalytic synthesis technology provied a new opportunity for the conversion and utilization of CO_(2).The bond breaking of C—H bond,C—O bond,C—N and C—X bond and carboxylation reactions with CO_(2)by photocatalysis strategy were systematically described.
