A single catalyst for sequential reactions: Dual homogeneous and heterogeneous behavior of palladium nanoparticles in solution

Abstract

One becomes two: Palladium nanoparticles stabilized by ionic liquids are used as the sole catalytic precursors for sequential Heck and hydrogenation processes. The dual role of these systems, which act as both a heterogeneous catalyst and also as a reservoir of catalytically active molecular species, is investigated. © 2009 Wiley-VCH Verlag GmbH& Co.
