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及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.

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 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, providing a sustainable and efficient method for the synthesis of β-keto phosphor(di)thioates.

Key words: visible-light-driven, bifunctional reaction, β-keto phosphor(di)thioate
