Director's cut: The pharmaceutically relevant sulfonamide group is shown to be a competent directing group for Cp*Rh(OAc)(2)-catalyzed C-H 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).
