the properties and reactivity of fluoromethylsulfonium salts resulted in the redesign of the reagents for fluoromethylene transfer chemistry. The model reaction, fluorocyclopropanation of nitrostyrene, turned out to be a suitable platform for the discovery of more streamlined fluoromethylene transfer reagents. The incorporation of halides on one aryl ring increased the reactivity, and 2,4-dimethyl substitution
对氟代甲基salts盐的性质和反应性的研究导致了氟代亚甲基转移化学试剂的重新设计。事实证明,模型反应(硝基苯乙烯的氟环丙烷化)是发现更多流线型氟亚甲基转移试剂的合适平台。在一个芳基环上引入卤化物可提高反应活性,而在另一个芳基环上进行2,4-二甲基取代可在试剂的反应性/结晶度和原子经济性之间取得平衡。通过开发有效的氟代环丙烷化方案以访问一系列单氟化环丙烷衍生物,证明了新试剂的实用性。
