A transition-metal-free t-BuOK-mediated reductive C–P cross-coupling reaction of arylvinyl sulfides with diarylphosphine oxides through C–S bond cleavage has been developed. This protocol not only permits the synthesis of diaryl(2-arylethyl)phosphine oxides, but also achieves an unprecedented construction of a C–P bond through C–S bond cleavage and reduction of a C–C double bond in one pot.

叔丁醇钾介导的芳基乙烯基硫化物通过 C-S 键裂解的还原性 C-P 交叉偶联

已经开发出一种无过渡金属的 t-BuOK 介导的芳基乙烯基硫化物与二芳基氧化膦通过 C-S 键断裂的还原 C-P 交叉偶联反应。该协议不仅允许合成二芳基（2-芳基乙基）氧化膦，而且还通过 C-S 键断裂和一锅 C-C 双键的还原实现了前所未有的 C-P 键构建。
