In the current work, the design, synthesis, characterization, and catalytic performance of a novel pseudopolymeric magnetic nanoparticles bearing urea linkers were presented. After the synthesis of urea linker, it was applied for the synthesis of pseudopolymeric magnetic nanoparticles. The structure of the synthesized pseudopolymeric magnetic nanoparticles was confirmed by applying different methods including Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray (EDX) analysis, thermo gravimetric analysis/differential thermal analysis (TG/DTG), transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), differential reflectance spectroscopy (DRS) and N2 adsorption-desorption isotherms. The catalytic performance of the titled structure was tested towards the synthesis of tetrahydrodipyrazolopyridine derivatives under mild reaction conditions.
