The reaction of the strong Lewis acid (C₂F₅)₃PF₂ with triethylamine leads to an initial hydride abstraction, resulting in the formation of the hydridophosphate anion [P(C₂F₅)₃F₂H]⁻ and the iminium ion [CH₃CH = NEt₂]⁺. The latter is deprotonated by a second molecule NEt₃ which corresponds to a formal hydrogen abstraction from the amine. The resulting nucleophilic enamine is trapped by a second equivalent of (C₂F₅)₃PF₂, ultimately yielding the β-aminovinylphosphorane derivative (C₂F₅)₂PF₂C₂H₂NEt₂. The β-aminovinylphosphorane reacts with CsF to the corresponding trifluorophosphate derivative, [P(C₂F₅)₂F₃C₂H₂NEt₂]⁻, which hydrolyzes to the aldehyde [P(C₂F₅)₂F₃CH₂CHO]⁻, while the reaction with anhydrous HF yields the zwitterionic species [P(C₂F₅)₂F₃C₂H₃NEt₂].

强路易斯酸（C ₂ F ₅）₃ PF ₂与三乙胺的反应导致最初的氢化物抽象，导致形成氢化磷酸根阴离子[P（C ₂ F ₅）₃ F ₂ H] ^-和亚胺鎓离子[CH ₃ CH = NEt ₂ ] ⁺。后者被第二个分子NEt ₃去质子化，第二个分子NEt ₃对应于从胺中抽出的氢。生成的亲核烯胺被第二当量的（C ₂ F ₅）₃ PF捕获_{如图2所示}，最终得到β-氨基乙烯基磷烷衍生物（C ₂ F ₅）₂ PF ₂ C ₂ H ₂ NEt ₂。β-氨基乙烯基磷烷与CsF反应生成相应的三氟磷酸酯衍生物[P（C ₂ F ₅）₂ F ₃ C ₂ H ₂ NEt ₂ ] ^-，后者水解为醛[P（C ₂ F ₅）₂ F ₃ CH _2个CHO] ^-，与无水HF反应生成两性离子物质[P（C ₂ F ₅）₂ F ₃ C ₂ H ₃ NEt ₂ ]。
