A combination of Pd(OAc)2 as a carboxylation catalyst and Ir(ppy)2(dtbpy)(PF6) as a photoredox catalyst enables a highly useful, visible-light-driven carboxylation of aryl bromides and chlorides under 1 atm of CO2 in high yields. This carboxylation reaction proceeds with various functionalized aryl bromides and chlorides without the necessity of using stoichiometric metallic reductants.
