Another method of diene diamination has been developed by Shi and coworkers.4 This variant is distinct from the remainder of the work discussed in this paper in that Pd0 initiates the catalytic cycle, and the nitrogen source, di-tert-butyldiaziridinone (2), functions as the oxidant. The mechanism is believed to involve an initial oxidative addition of 2 to Pd0, followed by alkene insertion to reach a palladium-π-allyl intermediateC,which proceeds similarly to other diene difunctionalization reactions.
