摘要

A new inorganic-organic hybrid material Al-SBA-15-TPI/H6P2W18O62 was prepared and fully characterized by SEM, XRD, FT-IR, TGA-DTA, and UV-Vis spectroscopic techniques. Then, the prepared nanomaterial was used as a simple, cost-effective, and reusable heterogeneous catalyst for the synthesis of 2H-indazolo 2,1-b phthalazine-1,6,11(13H)-trione derivatives by a one-pot, three-component condensation reaction of phthalhydrazide, cyclic diones, and aromatic aldehydes under solvent free conditions at 100 degrees C in a short time. This methodology has proven to be efficient and environmentally benign in terms of high yields and low reaction times and offers significant improvements with regard to the scope of transformation and simplicity of operation by avoiding expensive or corrosive catalysts.
