  氰尿酰氯催化可生物降解离子液体中酮肟的贝克曼重排

  摘要：

  在2,4,6-三氯[1,3,5]三嗪催化的酮肟的贝克曼重排中，侧链中含有酯部分的咪唑基离子液体（IL）已成功用作传统IL的替代物。该过程是温和的，并且适用于芳族和脂环族底物，以良好的定量收率提供重排产物。该过程是生态可持续的，因为这些IL是可生物降解的，此外，它们可以回收和再利用。

  This invention relates to ionic liquid (ILs) solvents for chemical synthesis based on an alkyl - imidazolium cation core containing ionic liquids which have enhanced biodegradability and reduced toxicity relative to existing imidazolium bases ILs such as 1-butyl-3-methylimidazolium (bmmim) salts. Many of the described ILs produce a score of over 60% biodegradability over 28 days in a biodegradability test such as the Sturm Test, the Closed Bottle Test (OECD 301D) or the CO2 Headspace Test (ISO 14593). The ILs of the invention comprise an alkyl substituted imidazolium cationic core having a -C=OX- side chain in the 3-position of the imidazole ring, wherein X = O, NH, N or S and an associated counteranion characterized in that the -C=OX side chain comprises at least one ether linkage. The biodegradable and non-toxic IL may be used as green solvents for the chemical, pharmaceutical, biofuel and biomass industries. The ILs of the invention are particularly useful in hydrogenation, pericyclic and metathesis reactions.

  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.
