, p. 113 - 121 (2013)
In this work, novel Br?nsted acidic ionic liquid 1,3-disulfonic acid imidazolium hydrogen sulfate {[Dsim]HSO4} is synthesized, and characterized by studying its FT-IR, 1H NMR, 13C NMR, mass, TG, DTG and XRD spectra. This ionic liquid, with three acidic functional groups, is utilized as a highly efficient, homogeneous and reusable catalyst for the preparation of hexahydroquinolines via one-pot multi-component condensation of arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione), β-ketoesters and ammonium acetate under solvent-free conditions. The catalyst can form dual hydrogen-bond using its SO3H groups which this subject can direct to its assembly and efficiency.
