QUICK LINKS

Di-tert-butylsilyl bis(trifluoromethanesulfonate) is a compound that functions as a strong and highly selective activator for a variety of nucleophiles, including alcohols, amines, and thiols. It acts as a Lewis acid, facilitating the activation of nucleophiles through the formation of stable intermediates. Di-Tert-Butylsilyl Bis(Trifluoromethanesulfonate) is known to promote a range of organic transformations, including silylation, glycosylation, and cross-coupling reactions, by effectively activating nucleophiles for subsequent reactions. Its mechanism of action involves the coordination of the trifluoromethanesulfonate groups to the silicon center, creating a highly electrophilic silicon species that can readily react with nucleophiles. Di-Tert-Butylsilyl Bis(Trifluoromethanesulfonate)′s ability to activate nucleophiles may be useful in the development of new methodologies and the preparation of complex organic molecules.
