Homogeneous organometallic as well as organomolecular catalysts were immobilized to the pores of amorphous inorganic supports with the aid of an ionic liquid as Pd-, Cu-, Ru-and Mac-SILC (SILC:Supported Ionic Liquid Layer Catalyst), which is a benign method to immobilize sophisticated but unstable homogeneous catalysts difficult so far to load in an inorganic support by a simple impregnation method. By immobilizing as a SILC, sustainability and reactivity of catalysts increased in Mizoroki-Heck reaction, Suzuki-Miyaura reaction, Huisgen [3+2] cycloaddition (click-reaction) without external ligand in aqueous media and ambient atmosphere, hydrogenation, olefin-metathesis reaction, and asymmetric Diels-Alder reaction. These SILCs could be repeatedly used after filtration.
