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.
Powerful silylating agent (see Appendix 4) and Lewis acid; compare tert-Butyldimethylchlorosilane, A13064 and 3429. Silylation of hindered alcohols can be effected with TBDMS-OTf and 2,6-lutidine, where other reagents are unsuccessful: Tetrahedron Lett., 22, 3455 (1981).
Has been used in a sequence for the conversion of N-Boc to N-Cbz: Tetrahedron Lett., 26, 5543 (1985). For an alternative method for this transformation, see Benzyl 2,2,2-trichloroacetimidate, A12387.
