Sol-gel silica-supported mineral acids (namely sol-gel perchloric acid (slg HClO4), sulfuric acid (slg H2SO4) and phosphoric acid (slg H3PO4), prepared by incorporating mineral acids molecules into silica via sol-gel technique, were used as an efficient heterogeneous catalyst for the direct addition...
