Trimethylsilyl Trifluoromethanesulfonate (CAS: 27607-77-8) ni kichocheo chenye nguvu cha asidi ya Lewis na wakala wa silaiti yenye ufanisi.Kawaida hutumika katika mzunguko wa Dieckmann-kama wa ester-imides na diesters, na pia hutumika kuandaa difluoroboron triflate etherate asidi ya Lewis yenye nguvu hasa katika kutengenezea asetonitrile.Trimethylsilyl Trifluoromethanesulfonate kwa ujumla hutumika athari zifuatazo:1.Silylation.TMSOTf hutumika sana katika ubadilishaji wa misombo ya kabonili hadi etha zao za enoli.Ugeuzaji una kasi zaidi ya 109 ukiwa na TMSOTf/triethylamine kuliko klorotrimethylsilane.Trimethylsilyl Trifluoromethanesulfonate ni triflate ya trialkylsilyl inayotumika kama kichocheo katika usanisi wa kikaboni.Inatumika pamoja na boroni trifluoride eth yl ether ili kuandaa asidi ya Lewis ambayo ina nguvu zaidi kuliko vipengele vyake na hasa ufanisi katika kutengenezea asetonitrile.
