제목 Base Catalysis via Amine-Functionalized Mesoporous Silicas with Various Structural Phases
초록 The tetraalkyl quaternary ammonium hydroxide functionalized mesoporous silica catalysts were prepared by the surface substitution reaction of chloropropyl-functionalized mesoporous silicas. Over these catalysts we conducted Claisen-Schmidt condensation of benzaldehyde and 2’-hydroxyacetophenone and subsequent Michael addition to give pharmaceutical important flavanone compound. Among the different mesostructure phases, the catalyst with Ia3d phase showed the highest catalytic activity which was due to the favorable diffusion and mass transfer for the substrate molecules into the bicontinuous cubic interwoven pore structure than other cubic and hexagonal structures.
