Resumo
Catalytic effect of three nanosized metal oxides TiO2, Al2O3 and Fe3O4 nanoparticles in the onepot synthesis of tetrahydrobenzo[a]xanthene-11-ones by three-component reaction of β-naphthol with aromatic aldehydes and dimedone has been studied. Various reaction conditions were tested in the presence of TiO2, Al2O3 and Fe3O4 nanoparticles. The results demonstrated that nano Fe3O4 was the more efficient heterogeneous catalyst than Al2O3 and Fe3O4. The reaction completed within shorter period of time under solvent-free conditions with higher yield. The catalysts used were recyclable.
