Versuchsvorschrift
A solution of 176 g of ethyl 1,1-diethoxyethyl(n-butyl)phosphinate in 540 ml of absolute dichloromethane containing 10% of absolute ethanol is treated with 143.6 g of trimethylchlorosilane. After stirring for 48 hours at room temperature, the solvent is removed in vacuo to afford a pale yellow oil. Distillation in vacuo affords ethyl n-butyl-phosphinate, b.p. 27°-34° (2×10-2 mbar).
