Abstract

Boehmite silica sulfuric acid (boehmite-SSA) has been prepared for the first time via an efficient sequential synthetic procedure. Initially, boehmite nanoparticles were prepared, coated by silica, and then reacted with chlorosulfonic acid to obtain boehmite-SSA. A simple, inexpensive, environmentally friendly and efficient procedure for the synthesis of polyhydroquinoline and 2,3-dihydroquinazolin-4(1H)-one derivatives using this compound as an efficient and novel nanocatalyst has been described. Boehmite-SSA is a stable, heterogeneous, cost-effective, easy to handle, and recoverable catalyst and can be reused for several consecutive runs without a significant loss of catalytic activity. Its structure was characterized by FT-IR spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction (XRD) and scanning electron microscopy (SEM).
