Description

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.
