Recent Advances in Reductive Functionalization of Carbon Dioxide with Borohydride Reagents

二氧化碳(CO_(2))是一种储量丰富、廉价易得、安全的可再生资源,通过化学转化实现对CO_(2)的资源化利用,获得高附加值的能源、材料及化工产品是达成“二氧化碳减排战略”的重要组成部分.然而,CO_(2)在其化学转化中常表现为热力学稳定性和动力学相对惰性,使其转化效率不高.因此,CO_(2)活化转化具有很大的挑战性.近几年来,利用CO_(2)的还原官能化反应制备高附加值的化学品取得了长足的进步.本文对硼氢化试剂在CO_(2)分子还原官能团化构筑C—N,C—C,C—O以及C—S键,合成有用的精细化学结构单元并获得高附加值化学品的研究进行了总结.硼氢化试剂廉价易得,对环境污染小,在使用过程中易于操作,对CO_(2)分子的还原效率以及获得的产物纯度和产率都较高.

Carbon dioxide(CO_(2))has shown great potential as an important one-carbon(C1)source in chemical feed-stock due to its low-toxicity,abundance,availability,and recyclability.The conversion and utilization of CO_(2) to value-added chemical products are important part of achieving“strategies for CO_(2) abatement”.Due to the high kinetic and thermodynamic stability of CO_(2),the high selectively reductive functionalization of CO_(2) to the value-added chemicals simultaneously is still desirable.In recent years,great progress in activation and incorporation of CO_(2) into valuable chemicals has been achieved.Herein,the reductive functionalization of CO_(2) using borohydride reagents is summarized.It mainly describes the hydroboration of CO_(2) in the presence of alkali metal borohydride,ammonia borane,and organic borane.
