Modified SBA-15 as an Efficient Environmentally Friendly Nanocatalyst for One-Pot Synthesis of Tetrahydrobenzo[b]pyrane Derivatives

摘要

SBA-15 mesoporous silicas modified with proline and aminopropyl functional groups were employed for synthesis of tetrahydrobenzo[b]pyrane derivatives by simply mixing the precursors with surface-modified catalyst in a mortar. The mesoporous catalysts were characterized by Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), small-angle x-ray diffractometry (SAXS), thermogravimetric/differential thermal analyzer (TG/DTA), Barrett-Joiner-Halenda (BJH) pore size and volume analysis, and Brunauer-Emmett-Teller (BET) surface area measurement methods. The results indicate that SBA-15 mesoporous silica modified with proline and aminopropyl functional groups can be effectively utilized for synthesis of tetrahydrobenzo[b]pyrane derivatives.View full textDownload full textKeywordsfunctional groups, SBA-15 mesoporous silica, tetrahydrobenzo[b]pyranederivativesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533174.2011.591646
