Procedure
Diphenylchlorophosphine (2.0 mL, 2.38 g, 10.79 mmol) was added to a stirred solution of diethylamine (2.5 mL, 1.82 g, 24.9 mmol) in toluene (20 mL). The resulting white slurry was stirred overnight at ambient temperature and filtered. The filtered solid was washed with toluene (2×10 mL). The combined filtrate was reduced in volume by distillation in vacuum to approximately 20 mL and transferred to a graduated Schlenk tube equipped with a Yong valve. The volume of the solution was adjusted to 31.0 mL by addition of toluene to give 0.348 M solution of Ph2PNEt2. 31P{1H} NMR (toluene, 25° C.), δ: 51.0 (s).
