摘要

本文报道了一种无需催化剂,利用可见光驱动的烯烃1,2-酮-(二)硫代磷酸酯化反应。该方法以叔丁基过氧化氢(TBHP)和S-氢(二)硫代磷酸酯作为双官能团化试剂,一步合成β-酮-硫代磷酸酯和β-酮-二硫代磷酸酯。初步的机理研究表明,关键的硫代磷酰自由基很可能是由S-氢(二)硫代磷酸酯直接光解产生的。此外,这种光化学方法具有反应条件温和、底物适用范围广的特点,同时无需添加金属、光催化剂或碱,为β -酮-(二)硫代磷酸酯的合成提供了一种可持续且高效的方法。

Abstract

A catalyst-free, visible-light-driven 1, 2-keto-phosphoro(di)thiolation of alkenes is reported. This method utilizes tert-butyl hydroperoxide (TBHP) and S-hydrogen phosphoro(di)thioates as difunctionalization reagents to produce β-keto phosphorothioates and β-keto phosphorodithioates in a single step. Preliminary mechanistic studies suggest that the key thiophosphoryl radicals are likely generated not via oxidation by TBHP, but through a direct photolysis of S-hydrogen phosphoro(di)thioates. Furthermore, this photochemical protocol features mild conditions and broad substrate scope while obviating the need for external metals, photocatalysts, or bases. This provides a sustainable and efficient method for the synthesis of β-keto phosphor(di)thioates.
