Popis: | Fe3O4@SiO2@Au nanoparticles were synthesized and characterized by FT-IR, XRD, SEM, AAS, VSM, EDS and XPS measurements. In this study we revealed that gold nanoparticles can act as an efficient catalyst in the regio- and diastereoselective one-pot reactions of aldehydes, dibromoformaldoxime and CH-acids like oxindole or 1,3-indandione. To the best of our knowledge, employing Au-based heterogeneous catalyst for the 1,3-dipolar cycloaddition reaction has not been previously reported. |
