Application:
Trimethylsilyl Trifluoromethanesulfonate (CAS: 27607-77-8) is a strong Lewis acid catalyst and efficient silylating agent. Usually used in a Dieckmann-like cyclization of ester-imides and diesters,and also used to prepare difluoroboron triflate etherate a powerful Lewis acid especially in acetonitrile solvent. Trimethylsilyl Trifluoromethanesulfonate is generally used following reactions:1. Silylation. TMSOTf is widely used in the conversion of carbonyl compounds to their enol ethers. The conversion is some 109 faster with TMSOTf/triethylamine than with chlorotrimethylsilane. Trimethylsilyl Trifluoromethanesulfonate is a trialkylsilyl triflate used as a catalyst in organic synthesis. It is used in combination with boron trifluoride eth yl ether to prepare a Lewis acid that is more powerful than its components and especially effective in acetonitrile solvent.
