N-Substituted hydroxylamines such as aroyloxy- or acyloxycarbamates were successfully employed as synthetically versatile amino precursors in the iridium-catalyzed direct C–H amidation of arenes. The reaction proceeds smoothly at room temperature over a broad range of substrates with high functional group tolerance to afford N-substituted arylamine products.
