Research Abstract	This study aims at developing liquid catalysts having ionic conductivity. By applying the molecular design that we developed earlier, a variety of ionic liquids were prepared from metal complexes having catalytic activities. First, Ru-containing ionic liquids were prepared from arene-Ru complexes bearing various bidentate ligands. These salts exhibited high catalytic activities toward the oxidation of alcohols, but the complexes were found to undergo gradual decomposition during the reaction. Second, Cu-containing ionic liquids were prepared from Cu complexes bearing tripod ligands. Ligands containing alkyl-imidazole moieties were designed. Cu(I) complexes were highly unstable; however, Cu(II) complexes were isolated as solids or highly viscous liquids.
