    用离子液体EMIMF(HF)2.3作为温和的HF源进行氟化
    摘要:
    氟化氢是一种基本的氟化试剂,但是处理起来很困难。为此,已经开发了一些改性的氟化试剂,例如HF-吡啶,Et 3 N-HF和聚(氟化氢)络合物。但是,这些试剂仍需要进行水溶液后处理程序,以产生氟化氢。近来,由于易于处理和非水后处理的可能性,离子液体受到了广泛的关注。在空气和湿气中稳定的离子液体3-乙基-1-甲基咪唑鎓低聚氟化氢(EMIMF(HF)2.3)可以用作某些氟化反应的氟化氢当量;它不需要水后处理。

  • Selective Halofluorination of Alkenes with Tetrabutylphosphonium Dihydrogentrifluoride in Combination with<i>N</i>-Halosuccinimide or 1,3-Dibromo-5,5-dimethylhydantoin
    作者:Yukitaka Uchibori、Masayuki Umeno、Hideharu Seto、Hirosuke Yoshioka
    DOI:10.1246/cl.1993.673
    日期:1993.4
    Alkenes and their functionalized derivatives were readily converted to the corresponding halofluorides with tetrabutylphosphonium dihydrogentrifluoride as combined with N-halosuccinimides or 1,3-dibromo-5,5-dimethylhydantoin in highly regio-, stereo-, and chemoselective manners. In particular, alkenes having a oxirane or primary hydroxyl group also underwent halofluorination selectively in good yields
    烯烃及其官能化衍生物很容易通过四丁基二氢三氟化鏻与 N-卤代琥珀酰亚胺或 1,3-二溴-5,5-二甲基乙内酰脲以高度区域选择性、立体选择性和化学选择性的方式转化为相应的卤代氟化物。特别是,具有环氧乙烷或伯羟基的烯烃也以良好的产率选择性地进行卤氟化。
  • Poly-4-vinylpyridinium Poly(Hydrogen Fluoride): A Solid Hydrogen Fluoride Equivalent Reagent
    作者:George A. Olah、Xing-Ya Li、Qi Wang、G. K. Surya Prakash
    DOI:10.1055/s-1993-25924
    日期:——
    Poly-4-vinylpyridinium poly(hydrogen fluoride) (PVPHF), containing 35-60% hydrogen fluoride by weight, was prepared as a solid hydrogen fluoride equivalent reagent. PVPHF with 60% hydrogen fluoride by weight was found to be a versatile fluorinating agent for the hydrofluorination and bromofluorination of alkenes and alkynes, fluorination of alcohols as well as other fluorination reactions. Low hydrogen fluoride content PVPHF (3 equivalents of hydrogen fluoride to 1 equivalent of 4-vinylpyridine unit) was also found to be an efficient reagent for bromofluorination of alkenes in the presence of 1,3-dibromo-5,5-dimethylhydantoin. Fluorosulfonic acid-modified PVPHF showed enhanced reactivities for the fluorination of secondary alcohols.
    聚-4-乙烯基吡啶聚(氟化氢)(PVPHF)是一种固态氟化氢等效试剂,含有35-60%的氟化氢(按重量计)。发现含有60%氟化氢的PVPHF是一种多功能的氟化试剂,可用于烯烃和炔烃的氟化氢化及溴氟化,醇的氟化以及其他氟化反应。低氟化氢含量的PVPHF(4-乙烯基吡啶单元1当量对应3当量氟化氢)在存在1,3-二溴-5,5-二甲基海因的情况下也被发现是一种有效的烯烃溴氟化试剂。氟磺酸修饰的PVPHF在第二醇氟化反应中显示出增强的反应活性。
  • Fluorination with ionic liquid EMIMF(HF)2.3 as mild HF source

    Hydrogen fluoride is a basic fluorinating reagent, but handling it is difficult. For this reason, some modified fluorinating reagents such as HF-pyridine, Et3N-HF, and poly(hydrogen fluoride) complex have been developed. Those reagents, however, still require aqueous work-up procedures which generate hydrogen fluoride. Recently, ionic liquids have received much attention because of the ease in handling

  • Halofluorination of Alkenes Using Trihaloisocyanuric Acids and HF×Pyridine
    作者:Marcio de Mattos、Pierre Esteves、Lívia Crespo、Rodrigo Ribeiro

    日期:2010.7
    Halofluorination of alkenes with a new system (trihaloisocyanuric acids and HF˙pyridine) results in the formation of vicinal halofluoroalkanes. The reaction is regioselective leading to Markovnikov-oriented products and the halofluorinated adducts follow anti-addition in the case of cyclohexene and 1-methylcyclohexene. Reaction yields range from 67-88%.
    在一种新系统(三卤异氰尿酸和氟化氢吡啶)作用下,烯烃的卤氟化反应会生成邻位卤氟烷烃。该反应具有区域选择性,倾向于生成Markovnikov定向产物,而且在环己烯和1-甲基环己烯的情况下,卤氟化的加合物遵循反向加成。反应产率介于67-88%之间。
