Pot‐economic synthesis of N‐aryl acridones was performed with 2‐aminobenzophenones and aryl boronic acids as starting materials. Cu‐catalyzed chelation‐assisted oxidative C–N cross‐coupling reactions were well merged with the following intra‐molecular oxidative dehydrogenative C–H amination reactions under an air atmosphere. The use of reagent capsules can further resolve the compatibility problem

A copper-catalyzed approach for the synthesis of N-arylacridones via sp(2) C-H bond amination using air as oxidant under neutral conditions is disclosed. This reaction not only provides a complementary method for synthesizing medicinally important acridones, but also offers a new strategy for sp(2) C-H bond amination.
