A novel nanomagnetic catalyst with Cl[DABCO-NO2]C(NO2)3 tags was designed, synthesized and fully characterized by several techniques such as Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, elemental mapping analysis, thermogravimetric analysis, derivative thermal gravimetric, powder X-ray diffraction patterns, field scanning electron microscopy, high resolution transmission electron microscopy, physical adsorption and desorption of N2 isotherms (BET) and vibrating sample magnetometer. The synthesized nanomagnetic particles were used as an efficient and recyclable catalyst for the one-pot three component condensation reaction of 3-methyl-1-phenyl-1H-pyrazol-5-amine or 3-methyl-1Hpyrazol- 5-amine, aryl aldehydes and malononitrile for the synthesis of pyrazolo[3,4- b]-pyridine derivatives under neat conditions.
