Transition-metal catalyzed carboxylation of organoboron compounds with CO2

Without slight doubt synthesis of carboxylic acids and their derivatives through the carboxylation reactions of organometallic compounds using CO2 as the raw material are one of the most attractive and hot research topics in the field of CO2 utilization. Therefore, broadening the scope of nucleophilic reagents for this appealing page of carboxylic acids synthesis is always interesting. Over the past few decades, organoboron compounds have aroused great interest in the organic chemistry community as promising organometallic reagents owing to their high stability, reactivity, safety, and easy accessibility. Not surprisingly, these compounds have recently found application in the area of CO2-fixation reactions. This review describes the achievements that have been reported on this fast-growing research arena.
