An efficient two‐step one‐pot procedure for the synthesis of unsymmetrical (hetero)aryl 1,2‐diketones has been developed. The reaction proceeds through a palladium‐catalyzed nucleophilic addition of potassium aryltrifluoroborates to aliphatic nitriles followed by a copper‐catalyzedaerobic benzylic C–H oxygenation using molecular oxygen as a green oxidant.
