lithiation of a dimethylphosphine sulfide), a two-step process of regioselective lithiation-trapping and silyl group removal has been used to prepare a range of P-stereogenic compounds, including precursors to diphosphine ligands (e.g., Mini-PHOS). This two-step protocol delivers products with the opposite configuration to that obtained by direct asymmetric lithiation−trapping of a dimethylphosphine sulfide
