چکیده | ||
Co@pyr/APTZCMNPs was synthesized, and some of its characteristic analyses, such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and X-ray diffraction (XRD) were investigated. The results indicated that this heterogeneous catalyst was an excellent and reusable system to synthesize of 14H-dibenzo[a.j]xanthene derivatives through a one-pot condensation of β-naphthol and arylaldehydes at 90 °C under solvent-free conditions. Due to the magnetic nature of the catalyst, it could be easily recovered by an external magnetic field and comfortable reused at least five times without loss of its catalytic activity. High yields of the desired product, easy recovery of the catalyst and solvent-free conditions were some of the advantages of our methodology. | ||
