Phenyl P,P-diphenylphosphinate → Potassium diphenylphosphinate

Participants

Reaction Steps

The procedure of Example 1 was followed adding neat solid phenyl diphenylphosphinate (5.88 g, 20 mmol) to a slurry of potassium trimethylsilanolate (2.56 g, 20 mmol) in dry tetrahydrofuran (50 mL); a 4 h reaction time was used. Potassium diphenylphosphinate (4.46 g, 87% yield) was isolated as a white solid: 1H NMR (D2O, DSS) δ 6.8-7.9 (m, Ar--H's, 10H). Anal. Calcd. for C12H10KO2P: C, 56.24; H, 3.93; K, 15.26; P, 12.09. Found: C, 52.57, 52.49, 54.53, 54.38; H, 4.00, 4.09, 4.02, 4.36; K, 14.78; P, 11.01, 10.89.
