An efficient CuFe2O4 nanocatalyst was created using the simple and cost-effective assisted sol gel method, which has been effectively worked with as an efficient catalyst for one-pot multicomponent synthesis of pyrano[2,3-c] pyrazoles starting from aromatic aldehydes, malononitrile, ethyl acetoacetate, and hydrazine hydrate. The synthesized catalyst was characterized by using Fourier transform infrared (FT-IR), X-ray diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), and transmission electron microscope (TEM) techniques. The synthesized organic compounds were examined using IR, 1H NMR, and 13C NMR spectroscopy. The yield of pyrano[2,3-c] pyrazoles was studied using various reaction parameters such as the amount of catalyst, type of solvent, reaction conditions, and time. The present work's significant advantages such as simple setup, mild reaction conditions, non-toxic solvents, high yields, simple purification, efficiency, and utilization of recovered materials after four cycles.
