Trimethylsilyl enol ethers bearing trialkylsilyl-protected hydroxy groups were converted into synthetically valuable bifunctional alkenyl nonaflates under the action of nonafluorobutane-1-sulfonyl fluoride combined with potassium fluoride in the presence of catalytic amounts of dibenzo-18-crown-6. The methodology has been demonstrated for structurally diverse substrates possessing various trialkylsilyl-protected hydroxy groups which remained intact during the reaction course.
