α‐C−H arylation of N‐alkylamides using 2‐iodoarylsulfonyl radical translocating arylating (RTA) groups is reported. The method allows the construction of α‐quaternary carbon centers in amides. Various mono‐ and disubstituted RTA‐groups are applied to the arylation of primary, secondary, and tertiary α‐C(sp3)−H‐bonds. These radical transformations proceed in good to excellent yields and the cascades
