Abstract

A novel approach towards the one-pot synthesis of aryl-14H-dibenzo[a,j]xanthenes is described from a known reaction between substituted aldehydes and β-naphthol in the presence of heterogeneous catalyst silica sulfuric acid under conventional heating as well as solvent-free conditions to afford good to excellent yields. The catalyst is reusable; it can be used several times without any decrease in the product yield.
