HCID 23680564Sodium diphenylphosphinateYield 98%

Procedure

In 2.18 g (10.0 mmol) of diphenylphosphinic acid (manufactured by Aldrich Inc., Product No. 10, 852-9), 20 mL (10.0 mmol) of 0.5 N sodium hydroxide was added, stirred at room temperature for 10 minutes, then water was distilled off under reduced pressure. The obtained solid was washed with a small amount of methanol and dried to obtain 2.35 g (yield 98%) of the aimed product as white crystal. Decomposition temperature: 469° C.
