چکیده
In this work, Fe3O4@nano-walnut shell/BIII (FNWSB), as a reusable and new catalyst was prepared then characterized by FT-IR, XRD, FESEM, EDS-MAP, TGA. This used for synthesis of tetrahydrobenzo[a]xanthen-11-ones via three-component, one-pot condensation reaction dimedone, β-naphthol, aromatic aldehydes. An uncomplicated work-up, high yields product, short times, use low-cost are considerable advantages procedure.
