Abstract:
Pentafluoropropionic acid was found to be highly efficient, and green catalyst for the synthesis of dibenzo[a, j] xanthenes by condensation reaction of β-naphthol with aryl aldehydes in good to high yields under solvent-free conditions. Present methodology offers several advantages, such as good yields, simple procedure with an easy work-up and the absence of any volatile and hazardous organic solvent.
Keywords:Dibenzo[a,j] xanthenes; pentafluoropropionic acid; solvent-free conditions; recyclable catalyst.
