Application:
tert-Butyldimethylsilyl Trifluoromethanesulfonate (CAS: 69739-34-0) is a highly reactive silylating agent and lewis acid capable of converting primary, secondary and tertiary alcohols to their respectctive TBDMS. TrifluoroMethanesulfonic acid tert-butyldiMethylsilyl ester is also used to covert ketones and lactones into their enol silyl ethers. TBDMS Triflate is used as a highly reactive silylating agent and Lewis acid capable of converting primary, secondary, and tertiary alcohols1b to the corresponding TBDMS ethers, and converting ketones and lactones, into their enol silyl ethers; promoting conjugate addition of alkynylzinc compounds and triphenylphosphine5 to α,β-enones; activation of chromones in [4 + 2] cycloaddition reactions;rearrangement of allylic tributylstannyl silyl ethers; activation of pyridine rings toward Grignard reagents and transalkylation of tertiary amine N-oxides;and transformation of N-t-butoxycarbonyl groups into N-alkoxycarbonyl groups.
