Chemical s main applications

Trimethylsilyl Trifluoromethanesulfonate is a trialkylsilyl triflate used as a catalyst in organic synthesis. Trimethylsilyl Trifluoromethanesulfonate is used in combination with boron trifluoride ethyl ether to prepare a Lewis acid that is more powerful than its components and especially effective in acetonitrile solvent. Trimethylsilyl is a common reagent used in a Dieckmann-like cyclization of ester-imides and diesters.
