Abstract

Abstract: The new synthesized sulfamic acid functionalized catalyst on the basis of calix[4]resorcinarene catalyzed successfully and efficiently the synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives through a one-pot condensation reaction of β-naphthol with various aryl aldehydes under thermal solvent-free conditions. As the major advantages of the present method, solvent-free and mild acidic conditions, catalyst recyclability, easy purification of the products, high yields along with relatively less reaction times can be mentioned. IR spectroscopy, field emission scanning electron microscopy and transmission electron microscopy are some of the spectroscopic methods used to characterize the new synthesized solid support.
