To facilitate the separation and subsequent reuse of the catalysts, immobilizations of homogeneous catalysts into the ionic liquid have been pursued for decades. In many cases, the catalysts can easily be immobilized in ionic liquids, and thus, separated by simple phase separation and recycled. In spite of their high potential as vehicles for catalysts immobilization, these systems still have a tendency to leach dissolved catalyst into the co-solvent used to extract the product of the reaction from the ionic liquid. To overcome or reduce the catalyst leaching, the imidazolium salt motif was incorporated into the ligand, catalyst-precursor or support materials providing the so called task-specific ionic liquids, resulting in enhancement of the catalyst reusability as well as in some cases, activity in conventional ionic liquids. Catalytic reactions such as hydrogenation, ring-closing metathesis, which have been carried out in ionic liquid by using task-specifically modified catalyst and support materials will be discussed.
