CO_2: C_1 Synthon in Carboxylation Reactions

基于资源与环境的考虑,以二氧化碳为原料的有机合成研究近年来日益受到科学家们的关注,其中以二氧化碳为C1合成子参与的过渡金属催化羧基化反应由于可有效构建各种羧酸类化合物及其衍生物,是二氧化碳利用和实现碳循环的理想途径之一。本文综述了催化活化二氧化碳与亲电试剂、烃类C—H键化合物、亲核试剂等通过构建新碳-碳键实现羧基化反应的最新研究进展。

Recently organic synthesis using carbon dioxide as the raw material has attracted considerable attention from scientists because of the resourceful and environmental factors. Especially, transition metal-catalyzed carboxylation reaction is an efficient method to construct carboxylic acids and their derivatives, which is regarded as one of ideal strategies for carbon dioxide utilization and carbon recycle. The recent advances of carboxylation reaction of CO2 with various substrates （electrophiles, hydrocarbons, nucleophiles） are reviewed herein.
