Abstract
CO2 is an important C1 source in organic synthesis due to its abundant, non-toxic and low-cost properties.Therefore, it is of great significance to use CO2 as a C1 source to synthesize compounds with high added value.This review focuses on the recent progress in the carboxylation of organic compounds using CO2 as an electrophile under electrochemical conditions.The electrochemical carboxylation of non-activated organic halides, unsaturated alkene compounds and some special compounds are mainly introduced.And the use of sacrificial anodes and non-sacrificial anodes is classified in detail.The reaction mechanisms of these reactions are also discussed.This review provides a reference for the application of such reactions in organic synthesis in the future.
