Abstract
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.
