AlCl3/SiO2 nano particles as a reusable catalyst for the synthesis of Synthesis of 14aryl-14H-dibenzo [a,j]xanthenes

The synthesis of 14-aryl-14H-dibenzno[a,j]xanthenes(3) has attracted considerable attention in organic synthesis. In thisarticle, aromatic aldehydes have been employed with 2-naphthol in the presence of AlCl3/SiO2 NPs under solvent-free conditions to afford the corresponding benzoxanthenes in very good yields. The use of readily available AlCl3/SiO2 NPs as a reusable and recyclable catalyst makes this process quite simple, convenient, and environmentally friendly.
