Abstract

1-Methylimidazolium tricyanomethanide {[HMIM]C(CN)₃} as a novel, green and nano molten salt catalyst was designed and fully identified by IR, ¹H NMR, ¹³C NMR, mass, thermal gravimetric (TG), derivative thermal gravimetric (DTG), X-ray diffraction (XRD) pattern, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses. The catalytic application of {[HMIM]C(CN)₃} for the one-pot three-component condensation reaction of various aromatic aldehydes, amides and β-naphthol was studied through the preparation of 1-amidoalkyl-2-naphthols at room temperature under solvent-free conditions in comparison with nano SnO₂. In the presented investigations, some products were produced and reported for the first time.
