A reagent system of trialkylsilyl trifluoromethanesulfonate and triethylamine cleaves readily tetrahydropyranyl ethers to give directly the corresponding trialkylsilyl ethers in good yields under very mild conditions. Dialkylsilylene derivatives of 1,3-diol can be obtained directly from the corresponding bis-tetrahydropyranyl ethers of 1,3-diol. And furthermore, alcohol tetrahydropyranyl ethers can be easily deprotected by treatment of trimethylsilyl trifluoromethanesulfonate alone to afford parent free alcohols in good yields.
