• Selective hydrogenation of trans-cinnamaldehyde and hydrogenolysis-free hydrogenation of benzyl cinnamate in imidazolium ILs
  作者：Saibh Morrissey、Ian Beadham、Nicholas Gathergood

  DOI：10.1039/b815566f

  日期：——

  trans-Cinnamaldehyde is selectively hydrogenated to hydrocinnamaldehyde using a commercially available palladium catalyst in novel imidazolium ILs. The selective hydrogenation extends to benzyl cinnamate, in which the ester is protected from hydrogenolysis under similar conditions.

  使用市售的钯催化剂在新型咪唑鎓离子液体中，反式肉桂醛可以被选择性地氢化为氢化肉桂醛。这种选择性氢化过程也适用于苄基肉桂酸酯，在该反应条件下，酯基得以避免氢解作用。

  Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics.
