Reactions of hexafluoro-1,4-naphthoquinone with phosphorus-centered bis-phenylphosphanes with structure Ph₂P(CH₂)_nPPh₂ (where n = 1–5) and Et₂P(CH₂)₂PEt₂ in various solvents (anhydrous C₆H₆, aq. C₆H₆, aq. dioxane, aq. DMSO, or MeOH) were investigated. It was shown that the use of aqueous dioxane and DMSO leads to target products of phosphanodefluorination (i.e., phosphorus-containing betaines and bis-betaines) with high yields. We found that the betaines upon purification by thin-layer chromatography underwent various transformations such as a ring contraction (thus yielding novel polyfluorinated indenones) or addition of an acetone molecule at the CO bond of the fluorinated 1,4-naphthoquinone. According to X-ray diffraction analysis, there were intermolecular F⋯π interactions in the crystal packing of all the obtained betaines. The interactions are characterized by short distances F⋯Cg from 3.151(5) to 3.831(2) Å (where Cg is a centroid of π-system).

六氟-1,4-萘醌的反应与磷为中心的双- phenylphosphanes与结构博士₂ P（CH ₂）_Ñ PPH ₂（其中n = 1-5）和Et ₂ P（CH ₂）₂ PET ₂在各种溶剂中（无水C ₆ H ₆，水溶液C ₆ H ₆，aq。二恶烷水溶液 研究了DMSO或MeOH）。结果表明，使用二恶烷水溶液和DMSO可以高收率地实现磷阳极氟化的目标产物（即，含磷的甜菜碱和双甜菜碱）。我们发现，通过薄层色谱法纯化后的甜菜碱经历了各种转化，例如环收缩（因此产生了新型的多氟茚满）或在氟化的1,4-萘醌的C O键处添加了丙酮分子。根据X射线衍射分析，所有获得的甜菜碱的晶体堆积中都存在分子间的F⋯π相互作用。相互作用的特征是从3.151（5）到3.831（2）Å的短距离F⋯Cg（其中Cg是π系统的质心）。
