Trifluoromethanesulfonic acid tert-butyldimethylsilyl ester Usage And Synthesis

Chemical Properties

clear colorless to yellow fuming liquid

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.
