摘　　要：二氧化碳自由基阴离子(CO_(2)^(-))是一种具有强还原性的活泼化学中间体,其作为羧基来源和单电子还原剂在有机合成反应及污水还原降解中具有广泛的应用.CO_(2)和甲酸及甲酸盐是常见的CO_(2)^(-)来源,能够通过单电子还原或氢原子转移过程转化为CO_(2)^(-).本综述总结了CO_(2)^(-)产生的机理及表征的方法,介绍了CO_(2)^(-)在各应用领域的最新研究进展,并对CO_(2)^(-)的应用前景提出了展望.Carbon dioxide radical anion(CO_(2)^(-))is an active chemical intermediate with strong reduction ability,which is used widely as C1-building block and single electron reducing reagent in organic synthesis.CO_(2) and formic acid or formate salts are common source of CO_(2)^(-).CO_(2)^(-)can be generated by either direct reduction of CO_(2) or hydrogen atom transfer(HAT)of formate salts.The production,characterization methods and application of CO_(2)^(-)are summarized,and the insights are provided into the prospects in this field.
