| Summary: | Abstract This study presents the synthesis of magnetic nanoparticles using commercially available precursors, including FeCl2·4H2O and C12H28O4Ti. The nanoparticles were coated with a silica layer and subsequently functionalized with 3-chloropropyltriethoxysilane (CPTES). To further enhance their properties, quinoline-2,4-dicarboxylic acid (QDA) was attached to the nanoparticles’ surface. A novel palladium (Pd) complex was then immobilized on the functionalized TiFe2O4 MNPs, resulting in a magnetically recoverable, highly efficient, and selective nanocatalyst. Comprehensive characterization of the nanocatalyst was carried out using techniques such as VSM, XRD, EDS, SEM, BET, TGA, XPS, TEM, FT-IR, and ICP. The results demonstrated that the TiFe2O4@n-Pr@QDA-Pd nanocatalyst exhibited excellent efficiency, notable selectivity, and impressive reusability in the synthesis of tetrazole derivatives via [3 + 2] cycloaddition between sodium azide (NaN3) and organic nitrile derivatives. |
