1,1-Difluoroethylated aromatics are of great importance in medicinal chemistry and related fields. 1,1-Difluoroethyl chloride (CH 3 CF 2 Cl), a cheap and abundant industrial raw material, is viewed as an ideal 1,1-difluoroethylating reagent, but the direct introduction of the difluoroethyl (CF 2 CH 3 ) group onto aromatic rings using CH 3 CF 2 Cl has not been successfully accomplished. Herein, we disclose a nickel-catalyzed 1,1-difluoroethylation of arylboronic acids with CH 3 CF 2 Cl for the synthesis of (1,1-difluoroethyl)arenes.
