Carbon dioxide (CO2) represents the most abundant and accessible carbon source in Earth. Thus the ability to transform CO2 into valuable commodity chemicals via construction of C-C bonds is an invaluable strategy. Carboxylic acids and derivatives, the main products obtained by carboxylation of carbon nucleophiles by reaction of CO2, have wide application in pharmaceuticals and
advanced materials. Among the variety of carboxylation methods currently available, the direct carboxylation of C–H bonds with CO2 has attracted much attention due to its advantages from a step- and atom-economical point of view. In particular, the prevalence of (hetero)aromatic carboxylic acid and derivatives among biologically active compounds has led to significant interest in the development of methods for their direct carboxylation from CO2. In this review will discuss the latest achievements in the area of direct C–H carboxylation of (hetero)aromatic compounds with CO2.
