Abstract

Photocatalytic generation of phosphoranyl radicals is fast emerging as an essential method for the generation of diverse and valuable radicals, typically via deoxygenation or desulfurization processes. This Perspective is a comprehensive evaluation of all studies using phosphoranyl radicals as tunable mediators in photoredox catalysis, highlighting how two distinct methods for phosphoranyl radical formation (radical addition and nucleophilic addition) can be used to generate versatile radical intermediates with diverse reactivity profiles.

摘要

光催化生成磷鎓自由基正迅速成为一种生成各种有价值自由基的重要方法，通常是通过脱氧或脱硫过程。这篇综述全面评估了所有将磷鎓自由基用作光氧化还原催化中可调介质的研究，强调了两种不同的磷鎓自由基形成方法（自由基加成和亲核加成）如何用于生成具有不同反应活性的通用自由基中间体。
