Abstract

PdCl2(NHC)2 complexes have been synthesized by the reaction of palladium acetate with a series of benzimidazolium and imidazolinium salts and characterized by elemental analysis, 1H NMR and 13C NMR spectroscopy. These complexes were used as catalysts for the intermolecular hydroamination reactions between styrene with various anilines in ionic liquid at 160 oC and corresponding anti-Markovnikov products were obtained with a selectivity of 100% in good yields.
