A convenient method for the preparation of imidazolium salts-functionalized mesoporous catalyst Me-Bmim-SBA-15 (2) by postgrafting [bmIm]OH on SBA-15 was developed. This catalyst presented excellent catalytic activities (more than 96% yields for all tested aldehydes) for Knoevenagel condensation of aldehydes and ethyl cyanoacetate under microwave irradiation in solid medium. Of particular note is that such a catalyst could be readily recovered and reused in the consecutively catalytic runs (up to 10 uses) while maintained high catalytic activity.
