Design, fabrication and characterization of magnetic nickel copper ferrite nanocomposites and their application as a reusable nanocatalyst for sonochemical synthesis of 14‑aryl‑14‑H‑dibenzo[a,j]xanthene derivatives

Abstract

In this research, 14-aryl-14-H-dibenzo[a,j]xanthene derivatives have successfully prepared through one pot reaction of the aldehyde derivatives and 2-naphthol employing the as-fabricated NiCuFe2O4 magnetic nanocatalyst under ultrasound irradiation. The structure of achieved derivatives was identified by using FT-IR, 1H NMR and melting point analyses. Moreover, FT-IR, XRD, FE-SEM, EDX, and VSM techniques were applied in order to verify the structure of NiCuFe2O4 magnetic nanoparticles. This protocol involves noticeable aspects such as; facile workup, saving costs, excellent yields, and reusability of the catalyst applying an external magnet. Furthermore, the used nanocatalyst was recycled and reused in five runs with slightly reduction in its catalytic activity.
