A visble-light-induced hydroaryldifluoromethylation of alkenes with α,α-difluoroarylacetic acids for preparation of difluoroalkylated arenes has been developed. This reaction proceeds through the hypervalent iodine reagent promoted decarboxylation and subsequent radical hydroaryldifluoromethylation.

silver-catalyzed decarboxylative radical addition/cyclizationreaction of α,α-difluoroarylacetic acids and acrylamides has been disclosed. The method provides a highly attractive approach to synthesize a series of difluorinated oxindoles that contain variousfunctional groups in moderate to good yields under mild conditions. Moreover, experimental studies reveal that the CF2 group of the α,α-difluoroarylacetic
