实验过程

Bromotrimethylsilane (43 mL, 0.326 mol) was added dropwise to cyclopropylmethyl-phosphonic acid diisopropyl ester (18.00 g, 81.8 mmol) stirred in a reaction flask chilled to 5° C. The resulting solution was allowed to warm to ambient temperature, stirred for three hours, and then concentrated by rotary evaporation yielding crude cyclopropylmethyl-phosphonic acid bis(trimethylsilyl) ester which was used without further purification.
