Abstract
A new method for the generation of the "PhSO2CF2Cu" species from readily available difluoromethyl phenyl sulfone (PhSO2CF2H) has been developed. The "PhSO2CF2Cu" reagent can be applied in (phenylsulfonyl)difluoromethylation of arylboronic acids, which affords a convenient approach to introducing the PhSO2CF2 group into aromatics.
