0 (T) Synonym: TMS triflate, TMSOTf, acid trimethylsilylester Trimethylsilyl is a derivate with a trimethylsilyl Rgroup. It has similar reactivity to trimethylsilyl chloride, and is also used often in organic synthesis. Synthesis of methyl triflate by the reaction of silver triflate with methyl iodide [23.

Later on Booth et al. [24 used triflic anhydride as a starting material for the synthesis of methyl triflate, CF3SO2OCH3, via reaction with methanol (Scheme 2). Scheme 2. Synthesis of methyl triflate by the reaction of triflic anhydride with methanol [24. Trimethylsilyl is a trialkylsilyl triflate used as a catalyst in organic synthesis. Trimethylsilyl 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.
