  One pot synthesis using supported reagents system KSCN/SiO2–RNH3OAc/Al2O3: synthesis of 2-aminothiazoles and N-allylthioureas

  摘要：

  A simple and efficient method has been developed for the synthesis of 2-aminothiazoles and N-allylthioureas from commercially available materials in one pot by using a supported reagents system, KSCN/SiO2-RNH3OAc/Al2O3, in which alpha-halo ketone reacts first KSCN/SiO2 and the product, alpha.-thiocyanatoketone, reacts with RNH3OAc/Al2O3 to give the final product, 2-aminothiazoles, in good yield and allyl bromide reacts with KSCN/SiO2 and the product, allyl isothiocyanate, reacts with RNH3OAc/Al2O3 to give N-allylthiourea.

  生物相容性离子液体促进环境条件下 2-Amino-4H-Chromenes 的一锅法合成

  摘要：

  通过一锅多组分反应合成2-氨基-4H-色烯由于其高原子效率和广泛的生物活性而备受关注。在这里，研究了一系列功能性离子液体对此类反应的催化性能，结果表明离子液体醋酸胆碱（[Choline][Ac]）可以在室温下有效地促进该反应，而无需有机溶剂。该反应易于进行，后续处理程序非常简单。通过萃取和洗涤程序即可获得纯品，无需柱分离程序。有趣的是，这个反应系统可以很容易地放大到几克，这表明它在工业应用中的前景。此外，离子液体 [Choline][Ac] 可以很容易地由廉价且具有生物相容性的材料制备，并且可以回收和再利用至少五个循环。在室温下，在乙酸胆碱的催化下，各种醛、丙二腈和活化酚可以转化为相应的 2-氨基-4H-色烯，分离产率从良好到极好。

  ability of certain surfactant ionic liquids to reduce the surface tension of aqueous solutions and to aggregate in the form of micelles, even at low concentrations, allowing their use as stabilizing or destabilizing agents in homogeneous polymerization in water/oil emulsions. Within this context, this work aims to verify the possible micellar properties of the ionic liquids. Critical micellar concentration

  通过电导技术分析了离子液体在水溶液中自行组织并产生聚集体的潜力，并使用了基于随机理论的新数学模型，以表明线性变化时刻。有可能分析这些聚集体的存在。由于某些表面活性剂离子液体具有公认的降低水溶液的表面张力并以胶束形式聚集的能力，即使在低浓度下也能用作稳定剂或去稳定剂，因此它在胶体和界面化学领域引起了人们的兴趣。在水/油乳液中进行均相聚合。在此背景下，这项工作旨在验证离子液体的可能胶束特性。获得了烷基羧酸铵离子的临界胶束浓度值。还表明，CMC与阳离子和熵因子的亲脂性基团直接相关。

  日期：2010.2.11

  This report describes the synthesis of ionic liquids that incorporate the N-methyl-2-hydroxyethylammonium cation with various carboxylic acid anions and the study of some of their physical properties, including self-diffusion coefficients, density, speed of sound, viscosity, and refractive index. H-1 and C-13 NMR spectra were used to characterize the chemical structure of the species in concordance with FT-IR spectra. DOSY NMR spectra was used to determine the self-diffusion coefficients of the components, which were consistent with the formation of a lamellar or micellar liquid-crystal phase in samples containing an alkyl chain in the anion species. Thermoacoustic parameters showed that anion alkyl chain has an influence on the molecular packing of these ionic liquids. In addition, the effect of temperature on the properties seems to be related to the size and the type of aliphatic chain of the ionic liquid.
