The functionalized ionic liquid (2,3-dimethyl-l-[3-N,N-bis(2-pyridyl)-propylamido] imidazolium hexafluorophosphate, [BMMDPA][PF6]) stabilized and modified palladium nanoparticles were obtained by reducing palladium(II) complex with molecular hydrogen. The as-synthesized palladium nanoparticles have been characterized by different methods. It was demonstrated that the Pd nanoparticles were very efficient catalysts for the selective hydrogenation of the C=C bonds of various functionalized alkenes under mild conditions in neat ionic liquid (1-n-butyl-2,3-dimethylimidazolium hexafluorophosphate, [BMMIM][PF6]). An efficient separation of the products from reaction mixture (ionic liquid phase) was realized and the catalyst's nano-dispersion and high performance could be preserved. (c) 2009 Elsevier B.V.
