Herein we reported a manganese promoted reductive cross‐coupling approach to construct P‒S bond. This is a practical method for the synthesis of mono‐thiophosphanes, bis‐thiophosphanes and tri‐thiophosphanes under mild conditions. The strategy featured a wide range of substrate scope including various disulfides and phosphine chlorides, constructing diverse sulfur‐containing organophosphorus compounds from inodorous and readily available starting materials. The employment of reductive conditions avoided the generation of phosphorothioates (PV) by‐products. Ultimately, gram‐scale synthesis and applications were explored. Extensive experiments indicated that the phosphine radical cascade process was involved in the catalytic cycle.

锰促进氯化膦与二硫化物的还原交叉偶联合成硫代膦


在此，我们报道了一种锰促进的还原交叉偶联方法来构建 P\u2012S 键。这是在温和条件下合成单硫代膦、双硫代膦和三硫代膦的实用方法。该策略具有广泛的底物范围，包括各种二硫化物和氯化膦，从无味且容易获得的起始材料中构建各种含硫有机磷化合物。采用还原条件避免了硫代磷酸盐 （PV） 副产物的产生。最终，探索了克级合成和应用。广泛的实验表明，膦自由基级联过程参与了催化循环。
