amount of copper reagents and use of expensive ligands. In an attempt to develop a mild, efficient and reusable system for copper catalyzed reactions, ethylacetoacetate was doped into ionicliquid (IL) by tagging it with imidazoliumcation stabilized by a counter hydroxide or acetate anion (4a and 4b). The novel ligand-anchored ILs demonstrated high efficiency in generation and stabilization of uniformly
