ABSTRACT
A considerably improved method for the Cu-catalyzed coupling of sulfuryl chloride with P(O)-H was described. Using commercially available l-proline as the ligand decreased the precatalyst loading, broadened the substrate scope and greatly promoted the efficiency of the coupling reaction. Moreover, gram-scale preparation, easy-to handle and recyclable catalyst featured this transformation.
