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 Fe 3 O 4 @TiO 2 ‐IL as nanocatalyst under solvent‐free condition. The products were prepared in good to excellent yields using Fe 3 O 4 @TiO 2 ‐IL magnetic nanocatalyst. The Fe 3 O 4 @TiO 2 magnetic nanoparticles (MNPs) were prepared using beet juice extract and functionalized with IL based on DABCO. Moreover, the core‐shell structured magnetic Fe 3 O 4 @TiO 2 ‐IL has been characterized by different techniques such as 1 H‐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.
