| Abstract | A rapid and efficient procedure for the preparation of various aryl-14H-dibenzo[a,j]xanthenes was reported. The method developed produced excellent yields via one-pot condensation of beta-naphthol with various aryl-aldehydes in the presence of Keggin vanadium substituted heteropolyacid, H5PW10V2O40, as catalyst under solvent free conditions. The present methodology therefore offered several advantages but not limited to excellent yields (82%-98%), short reaction times (30-50 min), mild reaction conditions, simple work-up, as well as the utilization of cheap and environmentally benign catalyst in the absence of organic solvents. |
