Intermolecular olefin hydroamination was studied by various Lewis acids. The results of ZrCl4, FeCl3, BiCl3, and AlCl3 catalyzed reactions of norbornene with aromatic amines were compared, and BiCl3 was found to be the most effective catalyst to give high yields for various amines, whereas ZrCl4 could promote the reactions at relatively low temperatures. The FeCl3 catalyzed reactions were the most chemoselective and excellent yields could be achieved for certain amines by using AlCl3. A carbocation mechanism was proposed, and the controllable syntheses of allylamine and tetrahydroquinoline from isoprene and 2,5-dichloroaniline were achieved by application of this mechanism.
