Difluoromethyl phenyl sulfone Chemical Properties,Usage,Production
Description
Difluoromethyl phenyl sulfone is a powerful nucleophilic difluoromethylation reagent due to the high reactivity of the sulfonyl-stabilized difluoromethyl anion towards many electrophiles including carbonyls, imines, alkyl halides, and cyclic sulfates and sulfamidates. In the nucleophilic reaction step, depending on the substrate structure, strong bases are used to generate the nucleophilic (phenylsulfonyl)difluoromethyl anion in situ. In the desulfonylation step, sodium/mercury amalgam and magnesium are the commonly used reductive reagents. Besides, the (phenylsulfonyl)difluoromethylated compounds can undergo β-elimination to afford gem-difluoroalkenes.
