氟负离子的碱性行为造成它本身或促使另一化合物具优良的亲核能力,因而可用来进行多种有机反应。例如氟负离子能促进对碳、氧、硫和氮原子中心的烃化,羧酸与卤代烃间的酯化,分子间缩合,环化,氧化,聚合及消除作用等。由于氟化物试剂较为稳定并可以回收,反应在基本中性条件下进行从而极大地避免副反应的发生,产率高,许多用普通碱不能进行 The basic behavior of fluoride anion causes itself or to promote another compound with excellent nucleophilic ability, which can be used for a variety of organic reactions. For example, fluorine anion can promote the carbon atoms of carbon, oxygen, sulfur and nitrogen atoms, esterification of carboxylic acid and halogenated hydrocarbons, intermolecular condensation, cyclization, oxidation, polymerization and elimination and so on. Since the fluoride reagent is relatively stable and can be recovered, the reaction is carried out under substantially neutral conditions, thereby greatly avoiding the occurrence of side reactions, high yields, many of which can not be carried out using common bases
