摘要: In this work, the novel bifunctional nanosized ionic liquid catalyst [4,4′-bipyridine]-1,1′-diium trinitromethanide (BPDTNM) was designed, synthesized, and characterized by using FT-IR spectra, 1H 13C NMR X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), high resolution transmission (HRTEM), thermogravimetry (TG), derivative (DTG) analysis, differential thermal analysis (DTA), HPLC-mass spectroscopy. The synthesized successfully applied to synthesis of 1-(benzoimidazolylamino)methyl-2-naphthol derivatives via a straightforward one-pot three-component condensation reaction 2-aminobenzimidazole, 2-naphthol, wide range aromatic aldehydes under mild solvent-free conditions.
