Trifluoromethanesulfonic acid tert-butyldimethylsilyl ester Chemical Properties,Uses,Production
Chemical Properties
clear colorless to yellow fuming liquid
Physical properties
bp 60°C/7 mmHg; colorless oil, d 1.151 g cm?3. Solubility: sol most organic solvents such as pentane, CH2Cl2, etc.
Uses
tert-Butyldimethylsilyl trifluoromethanesulfonate is involved in the introduction of a bulky tert-butyl dimethylsilyl group onto a cis-bis(alkenyl)oxirane used in Cope rearrangement. It is associated with a thiolane and promotes the chalcogenide-Morita-Baylis-Hillman reaction. Further, it is used as a highly reactive silylating agent. In addition to this, it is used to prepare enol silyl ethers by reacting with ketones and lactones.
Uses
t-Butyldimethylsilyl Trifluoromethanesulfonate 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.
Uses
TrifluoroMethanesulfonic acid tert-butyldiMethylsilyl ester 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.
Preparation
to 24 g (0.16 mol) of t-butyldimethylchlorosilane at 23°C under argon is added 14 mL (0.16 mol) of trifluoromethanesulfonic acid dropwise. The solution is heated at 60°C for 10 h, at which time no further hydrogen chloride evolves (removed through a bubbler). The resulting product is distilled under reduced pressure: 34 g (80% yield) of TBDMS triflate; bp 60°C/7 mmHg.
