Abstract :
in this research, zirconium fixed on the arabic gum (zrcl4@arabi gum) was used as a heterogeneous and recyclable lewis acid catalyst for the one-pot synthesis of 14-aryl-14h-dibenzo[a,j]xanthene derivatives from the reaction of 2-naphthol, and various aldehydes under solvent-free conditions and at 70 ᵒc. the present method has many advantages such as catalyst reusability, high yields, non-toxic, easy of operation, short reaction time, environmentally friendly and high efficiency.
