the corresponding monofluoroderivative in good yield. The synthesis of diethyl-1,1-difluoro-3-triisopropylsilylpropynephosphonate was efficiently achieved following Burton’s methodology using CuCl/Cd to promote the coupling reaction of diethyl bromodifluoromethylphosphonate with the corresponding alkynyl iodide. Although the solidphasesynthesis of α-hydroxy-γ-TIPS propargylphosphonate ester was carried
