Carbon dioxide is not only one of the greenhouse gases but also an appealing renewable C1 source. To reconcile the environmental benefit with chemical industry development, conversion of CO2 into valuable chemicals is proposed, and tremendous effort has been devoted to developing new synthetic protocols and highly efficient catalytic systems, wherein copper catalysis is attractive and features effective, inexpensive, and diverse transformation of CO2. Considering the ubiquity of the C–Cu bond in organic chemistry and the wide application of the resulting carbocuprate species in reductive coupling with electrophiles, C–Cu formation and subsequent CO2 insertion has been developed as an important strategy for CO2 chemical fixation, thereby resulting in the preparation of a variety of valuable chemicals. To arouse broad interest in this strategy, we summarize recent advances and give an overview on CO2 transformations via the carbocuprate species on the basis of the C–Cu bond formation mechanism, including copper-promoted alkyne and halide activation, transmetalation of some specific chemicals with copper, and hydrocupration, borocupration, and silylcupration of unsaturated substrates. It is hoped that this review can provide some clues for further exploration in this field.

C–Cu键的构建:CO 2转化的有用策略

二氧化碳不仅是温室气体之一,而且还是一种有吸引力的可再生C 1来源。为了使环境利益与化学工业的发展相协调,提出了将CO 2转化为有价值的化学物质的努力,并且已经付出巨大的努力来开发新的合成方案和高效的催化体系,其中铜催化具有吸引力,并且具有有效,廉价和多样化的特点。 CO 2的转化。考虑到C-Cu键在有机化学中的普遍性以及所生成的碳硼酸盐物种在与亲电试剂的还原偶联中的广泛应用,已开发出C-Cu的形成和随后的CO 2插入作为CO 2的重要策略化学固定,从而导致制备各种有价值的化学物质。为了引起人们对该战略的广泛兴趣,我们总结了最近的进展,并基于C–Cu键形成机理,包括铜助长的炔烃和卤化物的活化,某些特定化学物质的重金属化,概述了通过碳酸盐物种进行的CO 2转化。含铜,以及不饱和底物的加氢铜化,硼化铜化和甲硅烷基化。希望这篇综述可以为该领域的进一步探索提供一些线索。
