HCID 54365652Bis(trimethylsilyl) (3-phenylpropanoyl)phosphonate

Procedure

10.7 g of trimethylsilyl bromide were added dropwise at room temperature over a period of 1 hour to 8.5 g of dimethyl(3-phenylpropionyl)phosphonate. The mixture was then stirred for a further 1 hour and then evaporated at 30° C./0.1 mm Hg to give 12.5 g of bis(trimethylsilyl)-(3-phenylpropionyl)phosphonate in the form of a pale yellow oil. This oil was used in the next step without further purification.
