A general method for the N-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.
