We report a C–Ncross-couplingreaction of weakly nucleophilic N-arylsulfonamides and arylbromides to access N,N-diarylsulfonamides using Ni(cod)(DQ) as a catalyst without additional ligands. The process is compatible with electron-deficient and electron-rich aryl and heteroaryl bromides (34 examples, 21–98%) and can be applied to the derivatization of an N-arylsulfonamide pharmaceutical compound

An efficient, transition-metal-free procedure for the N-arylation of amines, sulfonamides, and carbamates and O-arylation of phenols and carboxylicacids has been achieved by allowing these substrates to react with a variety of o-silylaryl triflates in the presence of CsF. Good to excellent yields of arylated products are obtained under very mild reaction conditions. This chemistry readily tolerates
