Molecular iodine catalyzed synthesis of aryl-14H-dibenzo[a, j]xanthenes under solvent-free condition.
Molecular iodine efficiently catalyzes the reaction of beta-naphthol and araldehydes on a preheated hot plate at 90-95 degrees C to give biologically active aryl-14H-dibenzo[a, j]xanthenes under solvent-free condition. The yields are excellent and the reactions go to completion within 15-20 min.
