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.

An atom- and step-economical C(sp3)–H addition of N,N-dimethyl anilines to various sterically demanding 1,1- and 1,2-disubstituted alkenes has been achieved by using a simple β-diketiminato ligand supported scandium dialkyl complex in combination with a borate compound. The corresponding C(sp3)–C(sp3) bond forming reaction occurs with excellent regioselectivities to give a variety of tertiary aromatic
ortho-alkylation of N,N-dimethylanilines via C–H addition to alkenes was achieved for the first time using a cationic half-sandwich yttrium catalyst. This protocol constitutes a straightforward and atom-economical route for the synthesis of a new family of tertiary aniline derivatives with branched alkyl substituents, which are otherwise difficult to obtain. DFT calculation studies suggest that the interaction
