    分散在咪唑鎓离子液体中的镍纳米粒子的合成与表征。
    摘要:
    通过溶解在1-烷基-3-甲基咪唑鎓N-双(三氟甲磺酰基)酰胺离子液体中的[双(1,5-环辛二烯)镍(0)]有机金属前体的分解制备的镍纳米粒子的直径和尺寸分布取决于咪唑环的烷基侧链的长度。离子液体的组织范围顺序随着烷基侧链的增加而增加(从正丁基到正十六烷基),导致形成直径和尺寸分布较小的纳米粒子。由此制得的平均直径为4.9 +/- 0.9至5.9 +/- 1.4 nm且具有单峰尺寸分布的立方fcc Ni纳米颗粒可能由围绕Ni金属核的NiO小盖层组成。氧化物层的贡献还取决于介质,即 在侧链上含4至8个碳的盐中,金属氧化物的比例增加,然后随着碳数的增加而降低。分散在离子液体中的Ni纳米颗粒是用于在相对温和的反应条件下氢化烯烃的活性催化剂。

  • Reactivity of anionic nucleophiles in ionic liquids and molecular solvents
    作者:Cecilia Betti、Dario Landini、Angelamaria Maia
    DOI:10.1016/j.tet.2007.12.009
    日期:2008.2
    The nucleophilic reactivity of a representative series of anions has been measured in [hmim][ClO4] 3i, [hm2im][ClO4] 3′i, and [hmim][PF6] 3l ILs in the reaction with n-alkyl methanesulfonates and compared with that found in common molecular solvents (MeOH, DMSO, PhCl). The reactivity is found to depend on both the imidazolium cation–anion interaction and the specific solvation by water present in the
    在[hmim] [ClO 4 ] 3i,[hm 2 im] [ClO 4 ] 3'i和[hmim] [PF 6 ] 3l ILs中,在与n甲磺酸烷基酯,并与普通分子溶剂(MeOH,DMSO,PhCl)中的烷基磺酸盐进行比较。发现反应性既取决于咪唑阳离子与阴离子的相互作用,又取决于IL中存在的的特定溶剂化作用,起主要作用,尤其是亲性阴离子。去除最大量的可显着提高IL中的离子对反应性,直至速率常数k 与在DMSO和低极性介质(PhCl)中获得的结果相当。

    methylsulfonate anions (n = 8, 10 and 12, m = 1), the salts behave as conventional single chain cationic surfactants, showing a decrease of the CMC upon increase of the alkyl chain length (n) in the cation. When the amphiphilic character is present in both the cation and anion (n = 4 and 8, m = 4 and 8), novel catanionic surfactants with CMC values lower than those of the corresponding cationic analogues, and

    A set of 1-alkyl-3-methylimidazolium alkanesulfonate ionic liquids, [Cnmim][CkSO3], formed by the variation of the alkyl chain lengths both in the cation and the anion (n = 1–6, 8, or 10; k = 1–4, or 6), was synthesised, with sixteen of them being novel. The ionic liquids were characterised by 1H and 13C NMR spectroscopy, and mass spectrometry. Their viscosities and densities as a function of temperature, as well as melting points and decomposition temperatures, were determined. The molecular volumes, both experimental and calculated, were found to depend linearly on the sum (n + k).
    合成了一系列1-烷基-3-甲基咪唑硫酸烷基酯离子液体[Cnmim][CkSO3],其中阳离子和阴子的烷基链长度均可变(n = 1-6,8 或 10;k = 1-4 或 6),其中有16种为新型离子液体。通过1H和13C核磁共振波谱学以及质谱分析表征了这些离子液体。测定了它们的粘度和密度随温度变化的函数关系、熔点和分解温度。无论是实验测得的分子体积还是计算得出的,都发现与烷基链长度之和(n + k)呈线性相关。

    日期:2005.6
    The nucleophilic reactivity of a homogeneous series of anions (halides, pseudohalides and organic anions) in the ionic liquids [hexmim] [ClO4] and [hexmim] [PF6] has been measured in their reaction with n-alkyl methanesulfonates, and compared with that found in traditional molecular solvents of different polarity, that is, chlorobenzene, DMSO, and MeOH.
