双膦酸类化合物被认为是过渡金属催化中最普遍的特权配体结构。高原子经济性反应的发展对它们的合成具有重要意义，因为低原子经济性的方法往往需要在惰性气氛下进行复杂的纯化过程，以去除多余的起始原料和副产物。本文揭示了含PV(S)−PII单键的二膦单硫化物与烯烃的光诱导加成反应。这些反应只需要等摩尔量的二膦烷单硫化物相对于烯烃，并有助于在没有任何催化剂、碱或添加剂的情况下，在各种烯烃中高度选择性地引入两种不同类型的含磷基团，如硫代磷基和磷酰基。
Bis‐phosphanated compounds are regarded as the most ubiquitous privileged ligand structures in transition‐metal catalysis. The development of highly atom economical reactions is of great importance for their syntheses because less atom economical methods often require complicated purification procedures under inert atmospheres to remove excess starting materials and byproducts. Herein, the photoinduced addition reactions of diphosphane monosulfides bearing PV(S)−PIIIsingle bonds to alkenes is disclosed. These reactions require only equimolar amounts of the diphosphane monosulfide relative to the alkene and facilitate highly selective introduction of two different types of phosphorus‐containing groups, such as thiophosphoryl and phosphanyl groups, into a variety of alkenes without any catalyst, base, or additive.
