title: A highly efficient solvent-free synthesis of benzoxanthenes catalyzed by methanesulfonic Acid.
abstract: A series of 14-alkyl and aryl-14H-dibenzo[a, j]xanthenes have been synthesized through a one-pot condensation of beta-naphthol with alkyl or aryl aldehydes, in the presence of methanesulfonic acid in a solvent-free medium, with high yields.
