Ang Trimethylsilyl Trifluoromethanesulfonate (CAS: 27607-77-8) ay isang malakas na Lewis acid catalyst at mahusay na silylating agent.Karaniwang ginagamit sa isang tulad-Dieckmann na cyclization ng ester-imides at diesters, at ginagamit din upang maghanda ng difluoroboron triflate etherate ng isang malakas na Lewis acid lalo na sa acetonitrile solvent.Ang Trimethylsilyl Trifluoromethanesulfonate ay karaniwang ginagamit sa mga sumusunod na reaksyon:1.Silylation.Ang TMSOTf ay malawakang ginagamit sa pag-convert ng mga carbonyl compound sa kanilang mga enol eter.Ang conversion ay 109 mas mabilis sa TMSOTf/triethylamine kaysa sa chlorotrimethylsilane.Ang Trimethylsilyl Trifluoromethanesulfonate ay isang trialkylsilyl triflate na ginagamit bilang isang katalista sa organic synthesis.Ginagamit ito kasabay ng boron trifluoride eth yl ether upang maghanda ng Lewis acid na mas malakas kaysa sa mga bahagi nito at lalong epektibo sa acetonitrile solvent.
