Fluoride ion affinities (FIA), provided by DFT calculations, are exceedingly useful for the design of new Lewis acids with defined reactivities. Herein, we report the synthesis, characterization and reactivity of new difluoro(perfluoroorganyl) phosphoranes, which readily abstract fluoride ions from di-fluoro(triorganyl)phosphoranes. Highly reactive fluorobismuthonium cations and the [Ph3Bi(NCCH3)(2)](2+)
由 DFT 计算提供的氟离子亲和力 (FIA) 对于具有确定反应性的新路易斯酸的设计非常有用。在此,我们报告了新的二氟(全氟有机基)正膦的合成、表征和反应性,它们很容易从二氟(三有机基)正膦中提取氟离子。高活性氟铋阳离子和 [Ph3Bi(NCCH3)(2)](2+) 阳离子可通过用此处讨论的路易斯酸性正膦处理二氟(三有机基)铋(V)化合物来获得。
