Description

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.
