  SO3H-functionalized ionic liquids as efficient and recyclable catalysts for the synthesis of pentaerythritol diacetals and diketals

  摘要：

  The efficient, simple and environmentally friendly synthesis of pentaerythritol diacetals and diketals using SO3H-functionalized ionic liquids (ILs) as catalysts was reported. The ILs showed high catalytic activities and reusabilities with good to excellent yields of the desired products. H-0 (Hammett function) values and the minimum-energy geometries of SO3H-functionalized ILs were determined and the results revealed that the acidities and catalytic activities of ILs in acetalization were related to their structures. The IL [PSPy][OTf] with the shortest H-O bond distance had the strongest acidity and the highest catalytic activity in the synthesis of pentaerythritol diacetals and diketals. (C) 2010 Elsevier BM.

  The present invention concerns a catalyst system in particular a catalyst system comprising Palladium (Pd), a zwitterion and/or an acid-functionalized ionic liquid, and one or more phosphine ligands, wherein the Pd catalyst can be provided by a complex precursor, such as Pd(CH 3 COO) 2 , PdCl 2 , Pd(CH 3 COCHCOCH 3 ), Pd(CF 3 COO) 2 , Pd(PPh 3 ) 4 or Pd 2 (dibenzylideneacetone) 3 . Such catalyst systems can be used for e.g. alkoxycarbonylation reactions, carboxylation reactions, and/or in a co-polymerization reaction, e.g. in the production of methyl propionate and/or propanoic acid, optionally in processes forming methyl methacrylate and/or methacrylic acid. Catalyst systems according to the invention are suitable for reactions forming separable product and catalyst phases and supported ionic liquid phase SILP applications.

  本发明涉及一种催化剂体系，特别是包括钯（Pd）、一个伪离子和/或酸功能化离子液体，以及一个或多个膦配体的催化剂体系，其中Pd催化剂可以由复合前体提供，例如Pd(CH3COO)2、PdCl2、Pd(CH3COCHCOCH3)、Pd(CF3COO)2、Pd(PPh3)4或Pd2(dibenzylideneacetone)3。这种催化剂体系可用于例如烷氧羰基化反应、羧化反应和/或在共聚反应中，例如在生产甲基丙酸丙酯和/或丙酸中，可选地在形成甲基丙烯酸甲酯和/或甲基丙烯酸的过程中。根据本发明的催化剂体系适用于形成可分离产品和催化剂相以及支持的离子液体相SILP应用的反应。

  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.
