CO_2取代光气合成氨基甲酸酯研究进展

Progress in synthesis of carbamate by using CO_2 instead of phosgene

介绍了近几十年来利用CO2活化进行含氮化合物羰化反应合成氨基甲酸酯的研究进展。评述分析了各种金属盐催化、氨基甲酸盐阴离子作为亲核试剂、电解制备离子液体亲核试剂及超临界CO2条件下合成氨基甲酸酯反应过程的优点及不足,阐述了其反应机理,并对非光气法CO2合成氨基甲酸酯的前景做了展望。

The recent development of synthesis of carbamate by using CO2 as an activator is summarized. The merits and the shortages of the synthesis progress under the conditions of metal salt catalysts, carbamate anions, ionic liquid by electrochemical production and supercritical CO2 are introduced, and the reaction mechanism are also discussed. Further studies about synthesizing carbamate by using the non-phosgene method are also discussed.
