Catalytic Applications Of Supported Ionic Liquid Phases

Supported ionic liquids (SILPs), prepared via the immobilization of ionic liquids on solid material, can efficiently be used in catalytic reactions as catalysts, or as supports for transition metal catalysts. The SILP concept combines the advantages of homogeneous catalysis with those of heterogeneous systems. In the present paper, this is demonstrated with two examples. In the first application, acidic SILPs are shown to be selective and recyclable catalyst for the trimerization of isobutene. In the second example, neutral SILPs are proved to be excellent supports stabilizing palladium catalysts for carbonylation reactions, as well as ensuring effective catalyst recycling.
