We report the implementation of a consecutive photoinduced electron transfer (conPET) strategy for the functionalization of white phosphorus (P) with inexpensive and widely available aryl bromides and chlorides. By employing a well-known acridinium-based photocatalyst under near-UV irradiation, this protocol gives direct access to valuable triarylphosphines and tetraarylphosphonium salts. The reaction mechanism is elucidated by NMR spectroscopic studies and model reactions.
我们报道了一种连续光诱导电子转移（conPET）策略的实施情况，该策略用于用廉价且广泛可得的芳基溴化物和氯化物对白磷（P）进行官能化。通过在近紫外光照射下使用一种著名的基于吖啶鎓的光催化剂，该方案可直接获得有价值的三芳基膦和四芳基鏻盐。通过核磁共振光谱研究和模型反应阐明了反应机理。
