Triarylphosphines play a crucial role in organic synthesis as versatile components serving as ligands, catalysts, and reactants. This study introduces a metal-free, visible-light-induced method for the cross-coupling of cyanopyridines or polyfluoroarenes with diarylphosphines. This approach facilitates the formation of C(sp²)–P bonds through redox-neutral decyanative or defluorinative process, enabling the convenient synthesis of diverse triarylphosphines.

（杂）芳烃的光诱导、氧化还原中性脱氰和脱氟磷酸化


三芳基膦作为配体、催化剂和反应物的多功能组分在有机合成中发挥着至关重要的作用。本研究介绍了一种无金属、可见光诱导的氰基吡啶或多氟芳烃与二芳基膦交叉偶联的方法。这种方法通过氧化还原中性脱氰或脱氟过程促进C(sp ² )–P键的形成，从而能够方便地合成各种三芳基膦。
