The main feedstock for the value-added phosphorus chemicals used in industry and research is white phosphorus (P₄), from which the key intermediate for forming P(III) compounds is PCl₃. Owing to its high reactivity, syntheses based on PCl₃ are often accompanied by product mixtures and laborious work-up procedures, so an alternative process to form a viable P(III) transfer reagent is desirable. Our concept of oxidative onioation, where white phosphorus is selectively converted into triflate salts of versatile P₁ transfer reagents such as [P(L_N)₃][OTf]₃ (L_N is a cationic, N-based substituent; that is, 4-dimethylaminopyridinio), provides a convenient alternative for the implementation of P–O, P–N and P–C bonds while circumventing the use of PCl₃. We use p-block element compounds of type R_nE (for example, Ph₃As or PhI) to access weak adducts between nitrogen Lewis bases L_N and the corresponding dications [R_nEL_N]²⁺. The proposed equilibrium between [R_nEL_N]²⁺ + L_N and [R_nE(L_N)₂]²⁺ allows for the complete oxidative onioation of all six P–P bonds in P₄ to yield highly reactive and versatile trications [P(L_N)₃]³⁺.

用于工业和研究的增值磷化学品的主要原料是白磷（P ₄），其中形成 P(III) 化合物的关键中间体是 PCl ₃。由于其高反应性，基于 PCl ₃的合成通常伴随着产物混合物和费力的后处理程序，因此需要一种替代方法来形成可行的 P(III) 转移试剂。我们的氧化氧化概念，其中白磷被选择性地转化为多功能 P ₁转移试剂的三氟甲磺酸盐，例如 [P(L _N ) ₃ ][OTf] ₃ (L _N是阳离子、N基取代基；即，4-二甲氨基吡啶），为实现 P-O、P-N 和 P-C 键提供了一种方便的替代方案，同时避免了 PCl ₃的使用。_{我们使用 R n} E类型的 p 嵌段元素化合物（例如，Ph ₃ As 或 PhI）来获得氮路易斯碱 L _N和相应的双阳离子 [R _n EL _N ] ²⁺之间的弱加合物。_{[R n} EL _N ] ²⁺ + L _N和 [R _n E(L _N ) ₂ ] ²⁺之间的拟议平衡允许 P ₄中所有六个 P-P 键的完全氧化离子化，以产生高反应性和多功能的三阳离子 [P(L _N ) ₃ ] ³⁺。
