Ethyl Trifluoromethanesulfonate

Triflate, also known by the systematic name trifluoromethanesulfonate, is a functional group with the formula CF3SO3-. The triflate family is usually represented as -OTf in contrast to the group -Tf (triflyl). For instance, n-butyl triflate is expressed as CH3CH2CH2CH2OTf.

The triflate anion, CF3SO-3 is a very stable polyatomic ion. This result is due to its triflic acid (CF3SO3H) being a superacid, i.e. It is less acidic than pure sulfuric acid, which is already among the most powerful acids in the world.
