difluoromethyl phenyl sulfone, 95%, thermo scientific chemicals

Description :

Used as a reagent for the nucleophilic difluoro(phenylsulfonyl)methylation of carbonyls and fluorination. 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. Also used as reagent in preparation of α-difluoromethyl amines via stereo selective (phenylsulfonyl)difluoromethylation of chiral sulfinyl aldimines and Anti-difluoropropanediols via potassium tert-butoxide-catalyzed difluoromethylenation of aldehydes.
