A simple and efficient method has been developed for the synthesis of xanthene derivatives using various aromatic aldehydes and 2-naphthol under solvent-free conditions. In this procedure, ferric phosphate (FePO4) is used as an efficient and reusable heterogeneous Lewis acid catalyst for the synthesis of various derivatives of 14-aryl-14H-dibenzo[a,j]xanthene (3a-3m) in excellent yields (87-96%). The present method affords notable advantages such as short reaction time, simple workup procedure, reusability of the catalyst and high conversions of the products. All products have been confirmed by their melting points and spectroscopic techniques such as 1H NMR, 13C NMR, IR spectroscopy and mass spectrometry.
