Mode opératoire

Bromotrimethylsilane (15.3 mL, 0.116 mol) was added dropwise to 4-fluorophenyl-phosphonic acid diethyl ester (8.95 g, 38.58 mmol) stirred in a reaction flask chilled to 0° C. The resulting solution was allowed to warm to ambient temperature and stirred for an additional hour. The mixture was then concentrated by rotary evaporation yielding crude 4-fluorophenyl-phosphonic acid bis(trimethylsilyl) ester which was used in the next step without further purification.
