A novel non-hydrolytic sol-gel (NHSG) synthesis of mesoporous aluminosilicate xerogels is presented. The polycondensation between silicon acetate, Si(OAc)(4), and tris(dimethylamido) alane, Al(NMe2)(3), leads to homogeneous aluminosilicate xerogels containing Si-O-Al linkages through dimethylacetamide elimination. The addition of Pluronic P123 and F127 templates provides stiff gels that are, after calcination at 500 degrees C, converted to stable mesoporous xerogels with a high surface area (>600 m(2) g(-1)) and wormhole-type pores (d = 5.9 nm). The xerogels exhibit high catalytic activity in aminolysis of styrene oxide (82% conversion) with the turnover frequency up to 100.
