General Method

A general method for the <i>N</i>-arylation of sulfamides with aryl bromides is described. The protocol leverates a dual-catalytic system of nickel and a photoexcitable iridium complex and proceeds at room temperature under visible light irradiation. Using these tactics, aryl boronic esters and aryl chlorides can be carried through the reaction untouched. Thereby, this method complements known Buchwald-Hartwig coupling methods for N-arylation of sulfamides.

The first example of visible-light-driven reductive carboarylation of styrenes with CO<sub>2</sub> and aryl halides in a regioselective manner has been achieved. A broad range of aryl iodides and bromides were compatible with this reaction. <a>Moreover, pyridyl halides, alkyl halides and even aryl chlorides were also viable with this method.</a> 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 CO<sub>2.</sub>
