Description
Summary:A novel, green and reusable nano ionic liquid and catalyst, namely 1-methylimidazolium trinitromethanide {[HMIM]C(NO sub(2)) sub(3)}, was designed and fully characterized by super(1)H NMR, super(13)C NMR, IR, mass, X-ray diffraction patterns (XRD) and Transmission electron microscopy (TEM) analysis. The catalytic application of the presented catalyst was successfully tested on the Hantzsch four-component reaction of various aromatic aldehydes, 1,3-dione, beta -ketoester and ammonium acetate at room temperature under solvent-free and mild conditions to give the polyhydroquinoline derivatives in good to excellent yields. In the presented work, some products have been reported for the first time.
