Triethylsilyl Trifluoromethanesulfonate

Trimethylsilyl trifluoromethanesulfonate is a trifluoromethanesulfonate derived with a trimethylsilyl R-group. It exhibits a similar reactivity as trimethylsilyl chloride. It is often used in organic syntheses.

Silyl ethers are typically utilized as protective groups for alcohols used in organic syntheses. Because R1R2R3 is a combination of various groups, which can be modified to produce a variety of silyl-ethers, this chemical group provides an array of options for the protection of chemical groups.
