Abstract:

An expeditious and environmentally friendly approach for the synthesis of 14-aryl-14 Hdibenzo[ a,j]xanthenes via the multicomponent condensation reaction between different aromatic aldehydes and β-naphthol catalyzed by Nano-alumina sulfuric acid (N-ASA) under thermal and solventfree conditions has been studied. Notably, the present method offers desirable advantages of high yields, simplicity of work-up procedure, easy purification, reduced reaction times and reusability of the catalyst. Characteristics of nano-alumina sulfuric acid were determined using X-Ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and FT-IR spectroscopy.

Keywords: Aromatic aldehyde, condensation reaction, nano-alumina sulfuric acid, solvent-free conditions, xanthenes, β- naphthol.
