ABSTRACT This research introduces a simple method for sequential modification of ferrite nanoparticles. A novel, reusable, and green nanomagnetic heterogeneous catalyst was synthesized by immobilizing copper onto Fe 3 O 4 @THAM@PCH. Finally, it used as powerful new in the synthesis derivatives 2‐amino‐3‐cyanopyridine pyrano[2,3‐ d ] pyrimidine. In fabrication @THAM@PCH‐CuⅡ magnetic nanoparticles, incorporation tris (hydroxymethyl)aminomethane (THAM) demonstrated its efficacy cost‐effective easily accessible coating comparison to materials previously documented literature. The underwent comprehensive characterization through energy‐dispersive X‐ray spectroscopy (EDX), Fourier‐transform infrared (FT‐IR), vibrating sample magnetometer (VSM), diffraction (XRD), transmission electron microscopy (TEM), inductively coupled plasma (ICP), field emission scanning (FE‐SEM), thermogravimetric (TGA), map analysis. present method, known has advantages such operational approach, high product efficiency, mild reaction conditions, minimal chemical side products, short time. nanocatalyst can be recycled up 5 steps without noticeable decrease activity.
