Good Catalytic Activity

Five novel deep eutectic ionic liquids were prepared from relatively simple quaternary ammonium salts and imidazole. All of these salts are liquids at room temperature, and are steady up to 150°C. They exhibit low viscosities and moderate conductivities at low temperature. Especially, Bu4NCl-IM is a green alternative solvent in Sonogashira reaction with good catalytic activity.
