Herein, we present a (NH4)2S2O8 mediated difunctionalization reaction of aryl alkenes with quinoxalinones and P(O)SH compounds. This method enables the synthesis of various phosphorothioate‐containing quinoxalin‐2(1H)‐one derivatives (46 examples) in 37‐79% yields. The reaction is compatible with a range of functional groups and is easily adaptable to large‐scale synthesis. Preliminary studies suggest the involvement of phosphorothioate radicals in these transformations.

烯烃的多组分杂芳基硫代磷酸酯化用于获得 β-硫代磷酸酯喹喔啉酮

在此，我们提出了 (NH4)2S2O8 介导的芳基烯烃与喹喔啉酮和 P(O)SH 化合物的双官能化反应。该方法能够以 37-79% 的产率合成各种含硫代磷酸酯的喹喔啉-2(1H)-酮衍生物（46 个实例）。该反应与一系列官能团兼容，并且很容易适应大规模合成。初步研究表明硫代磷酸酯自由基参与了这些转化。
