Photoredox Catalysis as a Strategy for CO2 Incorporation: Direct Access to Carboxylic Acids from a Renewable Feedstock.

Carbon dioxide is an attractive reagent for organic synthesis from the standpoint of global sustainability. Its widespread use, however, is hampered by the fact that it is poorly reactive. New catalysts and technologies that enable C-C bond constructions are thus of high intrinsic value. This Minireview describes recent advances in the area of photoredox catalysis as an enabling strategy for promoting carboxylations.
