خلاصه مقاله:
A convenient and efficient direct protocol for the preparation of 14-aryl-14-Hdibenzo[a,j]xanthenes was described. The condensation of β-naphthol with various aromatic aldehydes in the presence of the catalytic amount of [H-NMP]+[HSO4]- under solvent free conditions at 110 °C was described. This method has the advantages such as; the reaction workup is very easy, and smoothly recycled to catalyze for the preparation 14-aryl-14-H-dibenzo[a,j]xanthenes with high yields by green and one-pot procedure.
