Application

Reagent Used for
  • Reductive silylation and the preparation of trifluoro- and difluoromethylsilanes by reductive coupling of fluoromethyl sulfones, sulfoxides and sulfides with chlorosilanes
  • Fluoroalkylation/chloroalkylation of α,β-enones, arynes, acetylenic ketones and other Michael acceptors
  • Difluoromethylation of primary alkyl halides via nucleophilic substitution-reductive desulfonylation

Reagent used in Preparation of
  • α-difluoromethyl amines via stereoselective (phenylsulfonyl)difluoromethylation of chiral sulfinyl aldimines
  • Anti-difluoropropanediols via potassium tert-butoxide-catalyzed difluoromethylenation of aldehydes
  • β-difluoromethylated and β-difluoromethylenated alcohols and amines by regioselective nucleophilic difluoromethylation of 1,2-cyclic sulfates and sulfamidates
  • Difluoroalkenes from alkyl halides via nucleophilic substitution-elimination
  • Difluoromethyl alcohol derivatives from enolizable and non-enolizable carbonyl compounds using nucleophilic phenylsulfonyldifluoromethylation-reductive desulfonylation strategy
  • Fluoromethylated vicinal ethylenediamines via fluoromethylation of chiral α-aminobutanesulfinimines with (phenylsulfonyl)fluoromethanes followed by reductive desulfonylation and alcoholysis

The diastereoselective nucleophilic (phenylsulfonyl)difluoromethylation and (phenylsulfonyl)monofluoromethylation of alpha-amino N-tert-butanesulfinimines (3) by using PhSO2CF2H and PhSO2CH2F reagents gave products 4 or 5 in high yields (73-99%) and with excellent diastereoselectivity (dr up to >99:1). After subsequent reductive desulfonylation and acid-catalyzed alcoholysis
A remarkably efficient fluoroalkylation of cyclic sulfates and sulfamidates with PhSO2CF2H: facile entry into beta-difluoromethylated or beta-difluoromethylenated alcohols and amines.
