Enantioselective addition of diethylzinc to benzaldehyde over mesoporous SBA-…

Abstract. Chiral proline derivative was anchored on mesoporous SBA-15 materials by nucleophilic substitution of chloropropyl-functionalized SBA-15 with (S)-(-)-a,a-diphenyl-2-pyrrolidinemethanol. Chloropropylfunctionalized SBA-15 prepared by co-condensation of tetraethyl orthosilicate and 3-chloropropyltrimethoxysilane using P123 copolymer as the pore directing agent in strong acidic environ…
