Application of nanosized Cu0.5Co0.5Fe2O4 spinel ferrite as a nanocatalyst in the synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives under solvent-free conditions

Abstract

Copper and cobalt substituted spinel ferrites Cu1-xCoxFe2O4 (0 ≤ X ≤ 1) have been synthesized by using hydrothermal method. The resultant spinel ferrites were systematically characterized by different techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FT-IR). It was indicated that all the resultant spinel ferrites obtained by the hydrothermal method had the single-phase crystalline. The resultant spinel ferrites were employed in the synthesis of 14-aryl-14-H-dibenzo[a,j]xanthene derivatives. It was found that the nanocatalyst Cu0.5Co0.5Fe2O4 displays the best performance in the synthesis of 14-aryl-14- H-dibenzo[a,j]xanthenes. The catalyst was reused several times without significant loss of its activity for the preparation of desired product. In addition, high yields of the products, solvent-free conditions and reusability of the catalyst are other worthwhile advantages of the present study.
