| solubility | Triethylsilyl Trifluoromethanesulfonate is readily sol hydrocarbons, dialkyl ethers, halogenated
solvents. CH2Cl2 is employed most commonly. Reactions in
1,2-dichloroethane proceed faster than those in CCl4 or Et2O.
Protic solvents and THF react with trialkylsilyl triflates and are
therefore not suitable. |

Description and Uses
Triethylsilyl trifluoromethanesulfonate acts as a silylating agent. It is also useful as a Lewis acid catalyst. Further, it reacts with 1-diazo-3,3-dimethyl-butan-2-one to prepare 1-diazo-3,3-dimethyl-1-(triethylsilyl)-2-butanone.
