as a new solid acid, was synthesized and fully characterized by fourier transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), scanning electron microscope (SEM), Energy-dispersive X-ray spectroscopy (EDX), thermal gravimetric analysis (TGA), 1H NMR and 13C NMR as well as mass spectra. [SO3H-4,4′-bipyridine-SO3H]Cl2 was successfully applied as a new and efficient catalyst for the

Solvent-Free Condensation of Phenols with Aldehydes and Amides Using 3-Methyl-1-sulfonic Acid Imidazolium Chloride
One-pot, three-component condensation of phenols, aromatic aldehydes, and amides in the presence of 3-methyl-1-sulfonic acid imidazolium chloride [Msim]Cl} as ionic liquid and catalyst under solvent-free condition to prepare a new category of compounds, namely amido-alkyl-phenols has been described. In the presented work, all products have been reported for the first time.
