ABSTRACT A new nanocatalyst, MNPs@AA:Cu, has been developed by immobilizing a Cu (II)‐aminoacetophenone‐Schiff base complex onto the surface of silica‐coated magnetite nanoparticles. The nanocatalyst was prepared using readily available reagents and thoroughly investigated FT‐IR, XRD, TGA, FE‐SEM, EDS, VSM, N 2 adsorption–desorption (BET) techniques. results confirm that MNPs@AA:Cu nanoparticles exhibit uniform size distribution with minimal aggregation demonstrate remarkable stability up to 250°C. Additionally, integrity Fe 3 O 4 core remains intact, coating shows no phase changes. catalytic activity sustainable heterogeneous catalyst evaluated in synthesis various biologically important benzimidazole derivatives from different benzaldehydes o ‐phenylenediamine under conventional heating solvent‐free conditions, resulting good excellent yields desired products. More importantly, catalyst’s magnetic properties enable it be easily recovered an external magnet reused six times without any significant decrease its or leaching copper.

In recent two decades, considerable efforts have been devoted to the room-temperature green syntheses of metal-organic frameworks (MOFs) reduce energy consumption and increase safety. It could improve some properties (e.g., catalysis, gas adsorption) facilitate utilities sensitive compounds. Herein, magnetic hybrid catalyst (Fe3O4@MOF-5) was synthesized through a mixing procedure at room temperature confirmed by various techniques. The SEM images exhibit cubic crystals that were uniformly coated Fe3O4 cores. Then, catalytic ability Fe3O4@MOF-5 studied in synthesis tetrahydropyridines via domino multi-component reaction, which led desired products with high yield. Magnetic solid make it easily separated from reaction medium, so proposed can be reused five times while maintaining activity over 80%.
