溶解度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.
