چکیده مقاله:
In this study, an efficient and rapid four component reaction of ethyl acetoacetate, hydrazine hydrate, malononitrile and different types of aldehyde has been developed. This reaction was carried out for synthesis of pyranopyrazole derivatives in the presence of CoCuFe2O4 magnetic nanoparticles in environmentally benign room temperature under solvent free conditions.The catalyst prepared and characterized by using Fourier transform infrared (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM) techniques. The products have been confirmed by spectroscopic and physical data such as; melting point, IR and 1H NMR analyses.
