Visible-Light-Driven Reductive Carboarylation of Styrenes with CO ₂ and Aryl Halides

Abstract

The first example of visible-light-driven reductive carboarylation of styrenes with CO₂ and aryl halides in a regioselective manner has been achieved. A broad range of aryl iodides and bromides were compatible with this reaction. Moreover, pyridyl halides, alkyl halides, and even aryl chlorides were also viable with this method. These findings may stimulate the exploration of novel visible-light-driven Meerwein arylation-addition reactions with user-friendly aryl halides as the radical sources and the photocatalytic utilization of CO₂.
