INTERMOLECULAR HYDROAMINATION OF STYRENE CATALYZED BY PALLADIUM(II) N-HETEROCYCLIC CARBENE COMPLEXES IN IONIC LIQUID

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, H-1 NMR and C-13 NMR spectroscopy. These complexes were used as catalysts for the intermolecular hydroamination reactions between styrene with various anilines in ionic liquid at 160 degrees C and corresponding anti-Markovnikov products were obtained with a selectivity of 100% in good yields.
