Ketone-Assisted Ruthenium(II)-Catalyzed C-H Imidation: Access to Primary Aminoketones by Weak Coordination

The ruthenium(II)-catalyzed intermolecular C-H imidation with weakly coordinating ketones provided step-economical access to synthetically useful primary aminophenones. The azide-free C-H imidation strategy occurred with ample scope and excellent functional group tolerance to efficiently deliver densely substituted aminophenones.
