Fig. 5: Utility of sodium diphenylphosphinite 2.

Reaction conditions: Ph2PONa 2 was prepared from 1.0 mmol Ph3P(O) in 5 mL solvent and 2.5 mmol SD according to the standard procedure. a 2.0 mL saturated aqueous NH4Cl solution was added to Ph2PONa 2 (1.0 mmol, in 1,4-dioxane) at 25 °C. b Ph2PONa 2 (1.0 mmol, in THF) was added to MesC(O)Cl (1.5 mmol) at 0 °C. c An alkyl halide (1.2 mmol) was added to Ph2PONa 2 (1.0 mmol, in THF) at 0 °C. Isolated yield.
