BiCl3-catalyzed hydroamination of norbornene with aromatic amines

A BiCl3-catalyzed hydroamination reaction of norbornene, in which a variety of electron-withdrawing groups were tolerated on amines, was presented. The current transformation possesses the advantages of being highly selective, cheap, and eco-friendly, and this process also represents a rare sys-tem for main-group Lewis acid catalyzed intermolecular hydroamination of unactivated alkenes.
