Abstract
In this study, quinazolinone derivatives have been synthesized via a suitable and efficient procedure by one‐potmulti‐component reactions of 3‐amino‐1,2,4‐triazole or 2‐aminobenzimidazole, dimedone and aromatic aldehydes in the presence of Fe3O4@TiO2‐IL as nanocatalyst under solvent‐free condition. The products were prepared in good to excellent yields using Fe3O4@TiO2‐IL magnetic nanocatalyst. The Fe3O4@TiO2 magnetic nanoparticles (MNPs) were prepared using beet juice extract and functionalized with IL based on DABCO. Moreover, the core‐shell structured magnetic Fe3O4@TiO2‐IL has been characterized by different techniques such as 1H‐NMR, FT‐IR, VSM, XRD, SEM, TGA, TEM and EDX. To the best of our knowledge, the prepared ionic liquid displayed a good protective and activator agent for magnetic nanocatalyst.
