Allylic amination reactions of alkenes, with an NBP (N-bromophthalimide) or NBS (N-bromosuccinimide)/DBU combination, were developed, 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 may provide a novel and complementary access

Reaction of N ‐arylsulfonyl allylamines with alkyl nitriles in the presence of di‐tert ‐butyl peroxide (DTBP) and a catalytic amount of copper salt afforded homologated aziridines in 43–86% yield. A sequence involving addition of the in situ generated cyanomethyl radical to the double bond followed by a copper‐mediated intramolecular C−N bond formation accounted for the reaction outcome. 2,3‐Disubstituted
