Abstract

In this research, Cu-phthalocyanine coated hybrid magnetic nanoparticles have been prepared in a simple method and evaluated as an efficient catalyst in the preparation of mono- and bis-pyrano[2,3-d]pyrimidinones and mono- and bis-2-amino-4H-pyrans from the condensation reaction of 1,3-dimethylbarbituric acid or 4-hydroxycumarin with malononitrile and mono- and bisaldehydes under ultrasonic irradiation. The catalyst could be easily recovered in the presence of the external magnetic field and reused five times without significant loss of activity and mass. The magnetic nanoparticles were characterized using Fourier Transform InfraRed (FT-IR) spectra, X-Ray Diffraction (XRD) spectroscopy, Scanning Electron Microscopy (SEM), Thermal Gravimetric Analysis (TGA). The results showed the spherical structures of hybrid magnetic nanoparticles and the average size is about 37 nm.
