What reactions occur with Trimethylsilyl trifluoromethanesulfonate (TMSOTf)? Is it harmful?

Trimethylsilyl trifluoromethanesulfonate (TMSOTf) is a highly electrophilic silylating reagent used extensively in organic synthesis for O- and C-silylation reactions. Its scope includes converting carbonyl compounds to enol ethers and facilitating reactions such as aldol-type condensations, glycosidations, and cyclizations. The reagent is utilized for the protection of hydroxyl groups and for promoting transformations that require activation of carbonyl and other electrophilic groups, making it essential for preparing enol ethers, silyl enolates, and silyl iminium ions. TMSOTf is a flammable liquid and vapour, it causes severe skin burns and eye damage.
