Irradiation of aromatic amines in the presence of alkyl nitriles leads to efficient electron-transfer reactions, resulting in amination or alkylation of the aromatic moieties.

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.

On the Superior Activity of In(I) versus In(III) Cations Toward <i>ortho-C-</i>Alkylation of Anilines and Intramolecular Hydroamination of Alkenes
ortho-C-alkylation of unprotected anilines with a variety of styrenes and alkenes using a univalent cationic indium(I) catalyst is reported. Mechanistic studies revealed that the reaction likely proceeds via a tandem hydroamination/Hofmann–Martius rearrangement. The high compatibility between the cationic indium(I) complex and primary anilines led us to develop an In(I)+-catalyzed hydroamination of alkenes

The first transition metal-catalyzed Friedel-Crafts alkylation of aromatic amines with styrene is reported. ortho-Alkylation of anilines occurs using catalytic amounts of [Rh(cod)2]BF4/4 PPh3 and HBF4.
Anti-Bredt di(amino)carbene supported gold(I) chloride complexes are readily prepared in two steps from the corresponding isocyanide complexes. In the presence of KB(C6F5)(4) as chloride scavenger, they promote the unprecedented hydroarylation reaction of alkenes with N,N-dialkylanilines with high para-selectivity. The latter are challenging arenes for Friedel-Craft reactions, due to their high basicity.
