Manganese Promoted Reductive Cross-Coupling of Phosphine Chlorides with Disulfides for the Synthesis of Thiophosphanes

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. Ultimately, gram-scale synthesis and applications were explored.
