Chemo- and Regioselective Hydroarylation of Alkenes with Aromatic Amines Catalyzed by [Ph3C][B(C6F5)4]

A nonmetal catalyst [Ph3C][B(C6F5)4] has been developed to catalyze hydroarylation reaction of alkenes with aromatic primary, secondary, and tertiary amines, which generated aniline derivatives in 32–98% yields. This method is applicable to a wide range of substrates, is highly chemo- and regioselective, and provides a simple and efficient approach for aniline derivative preparation.
