The Ir‐catalyzed mild CH amidation of benzoicacids with sulfonyl azides was developed to give reactions with high efficiency and functional‐group compatibility. Subsequent protodecarboxylation of ortho‐amidated benzoicacid products afforded meta‐ or para‐substituted (N‐sulfonyl)aniline derivatives, the latter being inaccessible by other CH functionalization approaches. The decarboxylation step
