Abstract
In this paper, the design, synthesis and catalytic application of a magnetic covalent organic framework modified with sulfonic acid (Fe3O4@COF-SO3H) in the synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives, were studied. The structure of the prepared catalyst was confirmed by various techniques including Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy, thermo-gravimetric analysis, field emission scanning electron microscopy, vibrating-sample magnetometer and Brunauer–Emmett–Teller porosimetry. The structure of the prepared derivatives was also confirmed using FT-IR and nuclear magnetic resonance (1HNMR and 13CNMR) spectroscopy. Facile synthesis, solvent-free conditions, high yield, short reaction time, eco-friendly procedure, and straightforward work-up are among the advantages of this research.
