A cationic Ir(I)-C3-TUNEPHOS complex catalyzed an intermolecularhydroamination of styrene derivatives with various heteroaromatic amines. The reaction gave Markovnikov products with perfect regioselectivity and good enantioselectivity under solvent-free conditions.

The base-mediated anti-Markovnikov hydroamination of functionally varied styrenes with amino-substituted pyridine, quinoline, pyrimidine, pyrazine, and phenanthridine with excellent regioselectivity has been described. Double hydroamination was observed chemoselectively on the secondary amine, leaving the primary amine intact. Experimental evidence suggests that the proposed reaction involves the nucleophilic
