Recent Advances in Light‐Induced Carboxylation of Organic (Pseudo)Halides with CO2

Abstract Carbon dioxide is an ideal C1 source in organic synthesis as a precursor for the carboxyl group. With the development of photocatalysis, the carboxylation reactions with CO 2 incorporation could be carried out in a more environmental and sustainable manner without the addition of stoichiometric metallic reductants. This minireview summarizes the recent development in light‐induced carboxylation of organic (pseudo)halides and analogues with CO 2 via C−X (X=Br, Cl, O, N, etc.) bond cleavage.
