Aromatic amines react with alkenes in the presence of catalytic amounts of aqueous HI to give mixtures of the corresponding hydroamination and hydroarylation products. While the hydroamination reaction is the preferred pathway for aliphatic alkenes, the hydroarylation reaction becomes more important when styrenes are used as substrates. In general, the electronic properties of the alkene and the amine strongly influence the efficiency and the selectivity of the reaction.

The intermolecular hydroamination of vinyl arene derivatives has been efficiently carried out using a tungstophosphoric acid (TPA) catalyst under solvent free and mild reaction conditions. The present protocol provides an environmentally benign, easy to handle and highly active solid acid catalyst for hydroamination of vinyl arenes. The catalyst yields both hydroamination and hydroarylation products and the selectivity mostly depends on the reaction conditions. (C) 2007 Published by Elsevier Ltd.
