Synthesis of 14-aryl/alkyl -14H-dibenzo [a,j] Xanthenes and Nitriles Catalyzed by KHSO4-SiO2 Under Ultra-sonication and Solvent-free Conditions

Abstract

14-Aryl/Alkyl-14H-dibenzo[a,j]Xanthenes and Nitriles were synthesized by a green, simple and highly efficient one pot synthetic method. The dehydration of 2-napthol with aldehyde leads to xanthenes and aldoximes to nitriles catalysed by KHSO 4-SiO 2 in neat and ultrasonication to afford the title compounds in high yields and relatively short reaction times.
