Arylenolacetates and DMF could promote radical difluoroalkylation of arylenolacetates to generate α,α-difluoro-γ-ketoacetates without a catalyst, an oxidant, or a base. When using different bases, β-fluoroenones and β-enaminones were synthesized by controllableC−Fbondactivation. These transformations provide an alternative method for the cascadedifluoroalkylation and C−F bonds activation of
