TiCl4-Catalyzed Intermolecular Hydroamination Reactions of Norbornene

Abstract: [reaction: see text] An intermolecular hydroamination reaction of norbornene is presented that uses catalytic amounts of user-friendly TiCl(4) and tolerates a variety of functional groups. In addition, a secondary amine is converted using this methodology.
