A catalytic regime for the direct phosphatation of simple, non‐polarized alkenes has been devised that is based on using ordinary, non‐activated phosphoric acid diesters as the phosphate source and O2 as the terminal oxidant. The title method enables the direct and highly economic construction of a diverse range of allylic phosphate esters. From a conceptual viewpoint, the aerobic phosphatation is entirely complementary to traditional methods for phosphate ester formation, which predominantly rely on the use of prefunctionalized or preactivated reactants, such as alcohols and phosphoryl halides. The title transformation is enabled by the interplay of a photoredox and a selenium π‐acid catalyst and involves a sequence of single‐electron‐transfer processes.

烯烃的光催化有氧磷酸化

基于使用普通的,未活化的磷酸二酯作为磷酸盐源,使用O 2作为末端氧化剂,设计了一种简单的非极化烯烃直接磷酸化的催化方案。该标题方法使得能够直接和高度经济地构建各种范围的烯丙基磷酸酯。从概念上讲,好氧磷酸化与传统的磷酸酯形成方法完全互补,后者主要依赖于使用预官能化或预活化的反应物,例如醇和磷酰卤。标题转换是通过光还原和硒酸催化剂的相互作用实现的,涉及一系列单电子转移过程。
