Direct C−H difluoromethylation of electron-deficient positions in nitrogen-containing heterocycles is attained by difluoromethyl radicals generated in-situ from difluoroacetic acid under silver-catalyzed oxidative decarboxylation. Control of the reaction temperature permits either mono- or disubstitution. More information can be found in the Communication by J. Nielsen et al. (DOI: 10.1002/chem.201704261).
