Room temperature ionic liquids were used as an environmentally benign solvent to synthesize benzyl cinnamate from potassium cinnamateand benzyl chloride in the presence of tetrabutylammonium chloride (TBAC). BMImBF4 has the best catalytic capability among the various kinds of ionic liquidsinvestigated and the reaction was found to proceed well under relatively mild conditions by the double catalytic system of ionic liquid/TBAC. The yield is up to 96.5%. The product could be conveniently separated, and the remaining ionic liquid/TBAC catalytic system could be reused for at least five times without muchlose in activities.

Key words: benzyl cinnamate, ionic liquid, catalytic synthesis
