Iridium-catalyzed direct ortho C-H amidation of arenes works well with sulfonyl- and aryl azides as the nitrogen source. The reaction proceeds efficiently with a broad range of conventional directing groups with excellent functional group compatibility under mild conditions via 5- as well as 6-membered iridacycle intermediates.
