In this paper, tris(hydroxymethyl) methylene ammonium acetate supported on GO as a new multifunctional heterogeneous catalyst was synthesized. After its characterization by different techniques such as FT-IR, TEM, FESEM, EDS, XPS, solid-state MAS NMR and elemental analysis, it was used as an efficient catalyst for the synthesis of hexahydroquinolines (HHQs) via a one-pot multi-component reaction. Different HHQs were synthesized in the presence of this heterogeneous metal-free catalyst in good to high yields at room temperature under solvent-free conditions. The catalyst was easily separated and reused at least five times without significant loss of activity. The acidic nature of GO improved the catalytic activity of the supported ILs and also provided heterogeneity to the ILs. This is the first report for the synthesis of HHQs in the presence of a multifunctional heterogeneous catalyst.
