Triarylbismuths were found to be highly efficient arylating reagents for copper-promoted N-arylation of secondary and some heteroaryl and aliphatic primary amines with over 49 examples. A variety of sterically diverse tertiary and secondary amines could be obtained in good to excellent yields with good functional group compatibility. The operational simplicity, mild reaction conditions as well as the
A simple approach for copper-promoted S-arylation reactions utilizing triarylbismuths or triarylantimonys as arylating reagents has been described. These reactions can be performed under mild conditions and exhibit remarkable functional group tolerance and chemoselectivity. The corresponding 2-arylthiopyridine 1-oxide derivatives and arylthioanilines/phenols have been successfully synthesized, achieving
