Descrizione

Descrizione generale

Tris(dimethylamino)sulfonium difluorotrimethylsilicate is widely used in organic synthesis as a source of fluoride ion for the synthesis of fluorinated compounds by C-F bond formation. It is also used as a reagent in hydrosilylation, cyanomethylation of ketones and Pd-catalyzed cross-coupling reactions.

Applicazioni

Tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF₂SiMe₃) can be used as a mild deprotecting reagent for the cleavage of silicon protecting groups.
It can also be used

• To synthesize deoxyfluoro sugars by reacting with trifluoromethanesulfonyl derivatives of partially protected sugars.
• As a reagent for the fluorination of hydroxyl-containing compounds.
