• Nano-WO 3 -supported sulfonic acid: New, efficient and high reusable heterogeneous nano catalyst

  日期：2015.1

  Nano-WO3-supported sulfonic acid [n-WO3-SO3H (n-WSA)] is easily prepared from the reaction of nano WO3 with chlorosulfonic acid as sulfonating agent. This new catalyst is characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), FT-IR spectroscopy, thermal gravimetric analysis (TGA), pH analysis and Hammett acidity function. Nano-WO3-supported sulfonic acid is used as an efficient and recyclable catalyst for some organic reactions such as synthesis of 1,8-dioxo-octahydroxanthene, tetrahydrobenzoxanthene and benzimidazolo quinazolinone derivatives. All of the reactions are very fast and the yields are excellent. The used catalyst was easily separated and reused for 10 runs without appreciable loss of its catalytic activity.

  reusable and efficient catalyst has been used for the preparation of 12-aryl-8,9,10,12-tetrhydro benzo[a]xanthene-11-one derivatives from the one-pot multicomponent reaction of aromatic aldehydes, β-naphthol, and a cyclic diketone under solvent-free conditions. Good yields, simple procedure, easy workup, short reaction times, and mild conditions are the advantages of this methodology. GRAPHICAL ABSTRACT
