In this study, an effective approach was developed to synthesize a novel, multifunctional ionic liquid nanocatalyst based on zeolite-Y with 4-methylpyridinium chloride (4-MePy-Cl) and calcium ions (Ca/4-MePy-IL@ZY). Then, Fe3O4 nanoparticles were produced inside the zeolite pores use of ultrasonic waves. XRD, FESEM, FT-IR, EDX-Map, TGA-DTA, VSM, BET, atomic absorption techniques used identify structure magnetic nanocomposite. its catalytic activity in one-pot synthesis 2-aminothiazoles using trichloroisocyanuric acid (TCCA) as green supplier halogen for intermediates studied. To provide ideal conditions preparation pure products, first, reaction acetophenone thiourea various solvents, different temperatures, presence amounts nanocatalysts molar amount TCCA used. Next, investigated 2-aminothiazole derivatives under optimal conditions. This method replaces iodine (I2), toxic reagent, first time TCCA, safe sustainable source halogen. The non-toxic solvent cheap, safe, recyclable nanocatalyst, quick times, high efficiency, ease separation aid magnet are additional benefits method. has led procedure being classified "green chemistry".

Abstract In this research, first, nanoporous zeolite‐NaY was functionalized with 3‐chloropropyltriethoxysilane (organic linker) and then N ‐methylimidazole group. Then magnetic nanoparticles (Fe 3 O 4 ) under ultrasonic energy conditions on the surface internal pores of zeolite‐Y (1‐MeIm IL@ZY‐Fe were formed. The identification, confirmation structure morphology prepared nanohybrid done by using FTIR, FESEM, TEM, EDX, TGA, XRD, VSM BET instrumental techniques. Next, its catalytic performance in synthesis a number 3‐benzimidazolyl (or benzothiazolyl)‐1,3‐thiazolidin‐4‐one derivatives investigated through three‐component condensation reaction various aromatic aldehydes, 2‐aminobenzimidazole or 2 ‐ aminobenzothiazole, thioglycolic acid EtOH at room temperature. results experiments show that presence inside zeolite ionic liquid not only causes easy quick separation nanocatalyst an external field but also can be effective catalyzing as Lewis acid.
