The combination of [Ir(ppy)2(dtbbpy)]PF6 as a photosensitizer, NiBr2·glyme as a precatalyst, and 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU) as a base enables an N-arylation of sulfamides with aryl bromides at room temperature under visible light irradiation. The reaction tolerates aryl boronic esters and aryl chlorides.
