Synthesis of imidazoles promoted by H₃PW₁₂O₄₀-amino-functionalized CdFe₁₂O₁₉@SiO₂ nanocomposite

H3PW12O40-amino-functionalized CdFe12O19@SiO2 nanocomposite has been applied as an effective nanocatalyst for the preparation of imidazoles by three-component reactions of benzil, ammonium acetate, and benzaldehydes under solvent-free condition. H3PW12O40-amino-functionalized CdFe12O19@SiO2 nanocomposites has been identified by powder X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectroscopy, vibrating sample...
