Ionic liquids as reagents and solvents in conjunction with microwave heating: rapid synthesis of alkyl halides from alcohols and nitriles from aryl halides
摘要:
We show that using ionic liquids as reagents in conjunction with microwave heating it is possible to prepare primary alkyl halides from the corresponding alcohols rapidly. Using ionic liquids as solvents in conjunction with microwave heating it is possible to prepare aryl nitriles from the corresponding aryl bromides or iodides. The scope and limitations of using microwave-promotion as a tool in these reactions is discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.

complexity of electrochemistry at the electrode-electrolyte interfaces that impacts the Coulombic efficiency, operational rate capability, and lifetime. Specifically, in energy-dense lithium metal batteries, the charging/discharging process results in structural heterogeneities of the metal anode, leading to battery failure by short-circuit and capacityfade. In this work, we take advantage of organic cations

We report the synthesis and characterization of a series of imidazolium iodide ionic liquids (ILs) containing monomethoxy-terminated poly(ethylene glycol) (mPEG), and n-alkyl groups. These PEGylated ILs contain 7, 12, or 16 ethylene glycol units in the sidechains, and are designed as potential electrolytes for energy conversion and storage devices such as dye-sensitized solar cells, supercapacitors
我们报告了一系列的合成和表征的碘咪唑碘化物离子液体(ILs)包含单甲氧基封端的聚(乙二醇)(mPEG)和n-烷基。这些PEG化的IL在侧链中包含7、12或16个乙二醇单元,并被设计为潜在的电解质,用于能量转换和存储设备,例如染料敏化太阳能电池,超级电容器和锂离子电池。使用一系列技术研究了这些目标应用至关重要的IL的热物理性质(密度,粘度和玻璃化转变,结晶和熔融的温度)和电化学性质(非法拉第窗以及电容器漏电耐受性),这些对这些目标应用至关重要。合成了1-烷基-3-甲基咪唑鎓碘化物ILs,并与PEG化ILs并行表征,以比较两个系统的电解质特性如何受到其详细的分子结构,尤其是醚氧原子的影响。mPEG侧链显示出与咪唑鎓环的强分子内相互作用,减弱了咪唑鎓阳离子与碘化物阴离子之间的库仑相互作用。因此,PEG化的ILs的电导率约为0.1 mS cm-1(25°C)尽管具有相对较高的粘度,但支持约2 V的
