H-indol-3-yl)butanoic acid 4aaa was designed against BPH and synthesized by two steps of N-alkylation. One-pot protocol towards 4aaa was newly developed. With IL [C6min]Br as solvent, the yield of 4aaa was increased to 75.1 % from 16.0 % and the reaction time was shortened in 1.5 hours from 48 hours. 25 Derivatives structurally based on arylpiperazine and indolyl butyric acid with alkyl linker were

The invention relates to new compounds containing alkyl/alkenyl-cyano- borate or alkyl/a!kenyl-cyano-fluoroborate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.
counter‐anions on activity and selectivity of the ethylenetrimerizationcatalysts based on Cr‐SNS‐R was investigated. All synthesized materials were characterized using Fourier‐transform infrared spectroscopy, 1H NMR, 13C NMR, UV–Vis. spectroscopy, thin‐layer chromatography, and elemental analysis (CHNS). In ethylenetrimerization reaction, the dodecyl substituent in the SNS ligand exhibited better activity
近年来,由于离子液体(ILs)在各个领域的广泛使用,引起了人们的极大兴趣。已在具有不同有机-无机杂化结构的离子液体中评估了几种三聚和低聚催化剂。与均相催化剂相比,双相催化剂体系的优点是高催化活性和选择性,易于产品分离以及催化剂的循环利用。在这项研究中,研究了IL抗衡阴离子对基于Cr-SNS-R的乙烯三聚催化剂的活性和选择性的影响。所有合成材料均使用傅里叶变换红外光谱,1 H NMR,13进行表征C NMR,UV-Vis。光谱学,薄层色谱和元素分析(CHNS)。在乙烯三聚反应中,SNS配体中的十二烷基取代基表现出比丁基取代基更好的活性和选择性。结果表明,高炉的存在4 -如在IL反阴离子导致相比于溴的增加的活性和选择性-和我-反阴离子。结果发现,在BF 4 -反阴离子起着1-己烯活性和选择性的发展一个决定性的作用的71132克最大量1 -C 6 /(克铬×h)和99%以上。最后,该催化剂可重复

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
