A nucleophilic aromatic substitution (S_NAr) reaction that allowed transition-metal-free C–P bond construction via C–N bond cleavage was developed. The coupling between aryltrimethylammonium salts and secondary phosphines from the in situ reduction of diarylphosphine oxides led to the formation of diverse triarylphosphines with various functional groups. This one-pot process was not only a pertinent S_NAr precedent but also a favorable transition-metal-free alternative for C–P coupling.

芳基铵盐一锅无过渡金属C-P偶联合成三芳基膦

开发了一种亲核芳族取代 (S _N Ar) 反应，该反应允许通过C-N 键断裂构建无过渡金属的 C-P 键。芳基三甲基铵盐与二芳基膦氧化物原位还原产生的仲膦之间的偶联导致形成具有各种官能团的多种三芳基膦。这种一锅法不仅是相关的 S _N Ar 的先例，而且是 C-P 耦合的有利无过渡金属替代方案。
