A combination of N-bromoimide and DBU enables allylic amination reactions of alkenes, in which both internal and external nitrogen nucleophiles can be installed directly. Dual activation of NBS or NBP by DBU leads to more electrophilic bromine and more nucleophilic nitrogen atoms simultaneously. This protocol provides a complementary access to allylic amination under mild conditions.
