Calcium chloride with one drop of conc. HCl was found facile and efficient catalyst for the synthesis of aryl 14H-dibenzo[a,j] xanthenes via one-pot condensation of various substituted benzaldehydes and β-naphthol under microwave and solvent-free conditions. The present protocol offers several advantages such as shorter reaction time, good to excellent yields, simple to operate, inexpensive and easily available catalyst.
