leads to unique properties, and perfluoroalkylationreagents play a vital role. Although various types of perfluoroalkylationreagents have been developed, existing nucleophilic perfluoroalkylationreagents suffer from chemical lability and limited structural diversity. This work aims to address these challenges by introducing a novel nucleophilic perfluoroalkylationreagent, 4-pyridyl perfluoroalkyl sulfide
将全氟烷基基团引入分子中会产生独特的性质,而全氟烷基化试剂起着至关重要的作用。尽管已经开发了各种类型的全氟烷基化试剂,但现有的亲核全氟烷基化试剂存在化学不稳定和结构多样性有限的问题。这项工作旨在通过引入一种新型亲核全氟烷基化试剂4-吡啶基全氟烷基硫醚(4-PySR f )来解决这些挑战,该试剂表现出基于N-硼基吡啶基阴离子的独特的全氟烷基阴离子释放机制化学。在二硼(4) 化合物和醇盐碱存在下,4-PySR f 有效地将全氟烷基转移到各种亲电子试剂上。值得注意的是,与其他已建立的试剂相比,它表现出优异的转移功能化全氟烷基基团、实现分子内全氟烷基化反应以及参与多步骤合成序列的适用性,为合成复杂的氟化分子提供了稳健的策略。这项工作扩大了 N-硼基吡啶基阴离子化学的合成潜力,并拓宽了亲核全氟烷基化反应的范围。

Oxidation of various fluoroalkyl-substituted methanol derivatives under the influence of a catalytic amount of sodium 2-iodobenzenesulfonate and Oxone® in CH3CN or CH3NO2 was investigated in detail. The efficiency of the newly developed oxidation was also evaluated by comparison to other oxidations, such as Dess–Martin, PDC, and Swern oxidation.
钠2-碘和过硫酸氢钾的催化量的影响下的各种氟烷基取代甲醇衍生物的氧化®在CH 3 CN或CH 3 NO 2详细进行了研究。通过与其他氧化方法(如Dess-Martin,PDC和Swern氧化方法)进行比较,还评估了新开发的氧化方法的效率。
