%X ferric hydrogensulfate as catalyst has been used for the one-pot preparation of aryl 14h-dibenzo[a,j]xanthene derivatives by cyclocondensation of ¦Â-naphthol and substituted benzaldehydes under solvent-free and thermal conditions. this method has the advantages of high yields, a cleaner reaction, simple methodology, short reaction times, easy workup and greener conditions.
