Nanostructure zeolite X; one-pot synthesis; 1,8-dioxooctahydroxanthene; 14-aryl-14Hdibenzo[ a,j]xanthene

A new modified zeolite containing Fe nanoparticles loaded in zeolite X (Fe-X) has been synthesized and characterized by FT-IR, XRD, EDX and SEM techniques and its catalytic activity has been investigated in the synthesis of two series of xanthene derivatives. We have described an efficient and novel method using Fe-X as a new and reusable catalyst for the synthesis of 1,8-dioxooctahydroxanthenes and 14-aryl-14H-dibenzo[a,j]xanthenes derivatives from one-pot three-component condensation of aromatic aldehyde and dimedone or b-naphthol under solvent-free conditions. The significant advantages of the present method are high yields of products, short reaction time, easy separation of the catalyst from the reaction mixture, easy product isolation, solvent-free condition and reusability of the catalyst
