TAS-F Chemical Properties,Usage,Production

  • Physical properties R = Me, mp 98–101 °C; R = Et, mp 90–95 °C.
  • Uses Tris(dimethylamino)sulfonium Difluorotrimethylsilicate is used in anhydrous fluoride ion source; synthesis of C–F compounds by nucleophilic displacement of sulfonates;promoter for electrophilic reactions of silyl enolates of ketones and esters; source of sulfonium cation capable of stabilizing or imparting high nucleophilic reactivity to other anions; activator of vinylsilanes in Pd-catalyzed cross-coupling reactions; also used for generation8 and reactions of α- and β-halo carbanions; hydrosilylation and cyanomethylation of ketones.
  • Uses 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.
  • Preparation The methyl derivative is prepared by the reaction of dimethylaminotrimethylsilane and sulfur tetra- fluoride at ?70°C to rt in ether; the precipitated solid is filtered off.1a The ethyl derivative is best prepared by the reaction of N,N-diethylaminosulfur trifluoride (DAST) and diethylaminotrimethylsilane.
  • General Description 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.
  • reaction suitability reagent type: reductant
