  A simple access to ω-aminoalkyltrialkoxysilanes: Tunable linkers for self-organised organosilicas

  摘要：

  A simple route to omega-aminoalkyltriethoxysilanes with variable alkylene chain lengths, (EtO)(3)Si(CH2)(n)NH2 (n = 5, 11) is described. These silyl linkers have been used to prepare urea-based compounds with H-bonding and hydrophobic interactions which enable the self-assembly of the molecules. These molecular precursors are suitable for the obtention of nano-structured hybrid silicas. (c) 2005 Elsevier B.V. All rights reserved.

  The highly reactive and chemoselective homogeneousdeallylation catalyst CpRu(η3-C3H5)(4-substituted-2-pyridinecarboxylato) was immobilized on microsize spherical Fe3O4@SiO2 particles. The resultant heterogeneous catalyst displays high saturation magnetization, weak coercive forces and high levels of dispersibility. The catalyst has increased the utility of deallylation by allowing the reaction to be

• Tuning Cooperativity by Controlling the Linker Length of Silica-Supported Amines in Catalysis and CO₂ Capture

  Cooperative interactions between amino-alkylsilanes and silanols on a silica surface can be controlled by varying the length of the alkyl linker attaching the amine to the silica surface from C1 (methyl) to C5 (pentyl). The linker length strongly affects the catalytic cooperativity of amines and silanols in aldol condensations as well as the adsorptive cooperativity for CO2 capture. The catalytic cooperativity increases with the linker length up to propyl (C3), with longer, more flexible linkers (up to CS) providing no additional benefit or hindrance. Short linkers (C1 and C2) limit the beneficial amine-silanol cooperativity in aldol condensations, resulting in lower catalytic rates than with the C3+ linkers. For the same materials, the adsorptive cooperativity exhibits similar trends for CO2 capture efficiency.
