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
据报道,使用 2-碘芳基磺酰基自由基易位芳基化 (RTA) 基团对 N-烷基酰胺进行 α-C-H 芳基化。该方法允许在酰胺中构建α-季碳中心。各种单取代和二取代的 RTA 基团适用于伯、仲和叔 α-C(sp 3 )-H-键的芳基化。这些自由基转化以良好到优异的产率进行,级联包括 1,6-氢原子转移,随后是 1,4-芳基迁移以及随后的 SO 2挤出。
