Director's cut : The pharmaceutically relevant sulfonamide group is shown to be a competent directing group for [Cp*Rh(OAc) 2 ]‐catalyzed CH functionalizations. Reactions of the cyclometalated intermediate with internal alkynes provide access to a wide range of sultam derivatives. The reaction is high yielding and works best under aerobic conditions with catalytic amounts of CuOAc as an oxidation mediator. Cp*=C 5 Me 5 .
