    Preparation, characterization and use of 1,3-disulfonic acid imidazolium hydrogen sulfate as an efficient, halogen-free and reusable ionic liquid catalyst for the trimethylsilyl protection of hydroxyl groups and deprotection of the obtained trimethylsilanes
    摘要:
    Novel 1,3-disulfonic acid imidazolium hydrogen sulfate, a halogen-free ionic liquid, is a recyclable and eco-benign catalyst for the trimethylsilyl protection of hydroxyl groups at room temperature under solvent free conditions to afford trimethylsilanes in excellent yields (92-100%) and in very short reaction times (1-5 min). Deprotection of the resulting trimethylsilanes can also be achieved using the same catalyst in methanol. The catalyst was characterized by IR. H-1 NMR, C-13 NMR and MS studies. All the products were extensively characterized by IR, H-1 NMR, MS, and elemental and melting point analyses. This new method consistently has the advantages of excellent yields and short reaction times. Further, the catalyst can be recovered and reused for several times without loss of activity. The work-up of the reaction consists of a simple separation, followed by concentration of the crude product and purification. (C) 2012 Elsevier B.V. All rights reserved.

    report an unconventional protocol for preparation of non-toxic immersion silver-plating solution/bath. The solution was prepared through electrolysis using ionic liquid (1, 3-disulfonic acid imidazolium hydrogen sulfate [Dsim] [HSO]) as electrolyte, metallic silver (Ag) as anode and copper as cathode. As a result of electrolysis, IL-capped aqueous charged silver ion (Ag) solution [colloidal Ag-IL adduct
    浸镀技术通常用于在印刷电路板 (PCB) 上进行均匀涂层的精加工。在此,我们报告了一种用于制备无毒浸镀溶液/镀液的非常规方案。该溶液采用离子液体(1, 3-二磺酸咪唑硫酸氢盐[Dsim][HSO])为电解液,(Ag)为阳极,为阴极,通过电解制备。电解的结果是获得IL封端的带电银离子(Ag)溶液[胶体Ag-IL加合物溶液]。通过循环伏安法 (CV) 实验验证了溶液中的存在。用 (NH-NH·H2O) 化学还原产生纳米。通过动态光散射 (DLS) 分析的 AgNP 的尺寸为 269.99 ± 14.2 nm,多分散指数 (PDI) 为 0.126。将条浸入溶液中,室温下 1-5 分钟内即可获得闪亮的镀表面。可以通过改变浸泡时间来控制膜厚度。通过Tafel拟合发现腐蚀速率为0.0012mm/a。该溶液可稳定数月而不会损失效率,而回收的 IL 使用五次也不会显着损失效率。
