We report the preparation, characterization and exploitation of 1,3-dialkylimidazolium dimethyl phosphates. Condensation reactions of benzaldehyde with ethyl cyanoacetate and with malonic acid were performed in these ionic liquids either in absence or in presence of other catalysts. The effect of ionic liquid structure on the condensation reaction rates and yields was discussed
