A highly regioselective ruthenium‐catalyzed C–H amidation of cyclic N ‐sulfonyl ketimines with organic sulfonyl azides is described. An alkenylation at the C–H bond of cyclic N ‐sulfonyl ketimines with various alkenes was also carried out. Only a catalytic amount of the oxidant Cu(OAc) 2 was used in the reaction; the remainder of the required amount of oxidant was formed by regeneration of Cu(OAc) 2 under an air atmosphere.
