The chemical conversion of carbon dioxide,a non-toxic,non-flammable,abundant and cheap renewable C1 resource,into high value-added organic compounds has become an important strategy for sustainable development.Among various transformations,CO2 as the carboxylating agent for the synthesis of carboxylic acids and derivatives has attracted much attention in the field of activation and conversion of CO2.This review summarizes the progress in carboxylation of unsaturated hydrocarbons with CO2 catalyzed by transition-metal catalysis in recent years.%CO2是一种无毒、廉价易得、储量丰富的可再生资源,通过化学方法将其转化为具有高附加值的化学品已成为实现可持续发展的战略性课题.其中,以CO2作为羧化试剂合成羧酸及其衍生物的研究成为CO2催化活化领域的研究热点.本文分类介绍了不同过渡金属催化的不饱和烃与CO2的羧化反应方面的研究进展.
