A new solid-supported palladium catalyst was prepared and proved to be highly effective catalyst for the Suzuki reaction. For this, N-heterocyclic carbene Palladium (NHC) complexes in an imidazolium-type Ionic Liquid matrix were prepared and immobilized on a silica surface. The Suzuki reaction was carried out in an aqueous medium at room temperature. After the reaction the catalyst was recovered quantitatively by simple filtration. The catalyst revealed its full catalytic activity even at a low temperature. The reaction was completed in a short reaction time with small amounts of the catalyst. The catalyst could be recycled several times without significant loss of its catalytic activity
