Under ethanol and solvent-free conditions, 1,1'-alkyl(aryl)-bis(naphthalen-2-ol) and 14-alkyl(aryl)-14H-dibeno[a,j]xanthenes were successfully synthesized from β-naphthol and aldehydes by using silicotungstic acid with keggin structure as the catalyst. The reaction catalyzed by silicotungstic acid has the advantage of short reaction time, high yield, simple workup procedures and easy isolation. The catalyst was inexpensive and environmentally friendly.

Key words: xanthene, aldehyde, β-naphthol, silicotungstic acid
