  • Vicarious nucleophilic substitution of hydrogen versus vinylic substitution of halogen in the reactions of carbanions of halomethyl aryl sulfones with dialkyl halofumarates and halomaleates
    作者:Mieczysław Mąkosza、Shamil Nizamov、Andrzej Kwast
    DOI:10.1016/j.tet.2004.04.049
    日期:2004.6
    halomethyl aryl sulfone carbanions with dialkyl halofumarates and halomaleates results in nucleophilic substitution of hydrogen and/or of the halogen. The reaction with halofumarates proceeds via addition of the carbanions to the vinylic carbon atom connected with hydrogen, followed by base promoted β-elimination of hydrogen halide in which the halogen originates from the carbanion moiety or from the alkene
    卤代甲基芳基砜碳负离子与卤代富马酸二烷基酯和卤代马来酸酯的反应导致氢和/或卤素的亲核取代。与卤代富马酸酯的反应是通过向与氢连接的乙烯基碳原子上添加碳负离子,然后通过碱促进β-消除卤化氢而进行的,卤中的卤素源自碳负离子部分或烯烃。在卤代甲酸酯的情况下,反应通过消除加成序列进行。
  • Stereoselective Hydrohalogenation of Alkynoic Acids and Their Esters in Ionic Liquids
    作者:José Salazar、Francys Fernández、Jelem Restrepo、Simón E. López
    DOI:10.3184/030823407x200038
    日期:2007.3
    A novel procedure is described for the hydrohalogenation of alkynoic acids and their esters using N-alkylpyridinium ionic liquids. Hydrohalogenating agents were prepared by mixing N-alkylpyridinium halides with an equimolar amount of trifluoroacetic acid. The corresponding halogenated alkenes were obtained in good yields with high diastereoselectivity.
    描述了一种使用 N-烷基吡啶鎓离子液体对炔酸及其酯进行氢卤化的新方法。通过将 N-烷基吡啶鎓卤化物与等摩尔量的三氟乙酸混合来制备氢卤化剂。以良好的收率和高非对映选择性获得了相应的卤代烯烃。

    afforded a mixture of end-capped oligomers, from which 11–13 were isolated by column chromatography (Scheme 3). The poly(triacetylenes) (PTA) 16–18 were prepared in a similar manner starting from diol 8 and stearic acid (Schemes 4 and 5). Whereas the end-capped monomers and dimers 11, 12, 16, and 17 with pendant long alkyl chains do not exhibit any liquid-crystalline behavior, the trimeric derivatives 13
