2,4-Dinitrophenylhydroxylamine (1) is an efficient reagent for the iron-catalyzed regioselective allylicamination of olefins. Moderate to excellent yields of N-DNP-N-allyl amines (2) are obtained resulting from introduction of the N-DNP group at the less substituted vinylic carbon with accompanying double bond transposition. N-alkylation of 2 and subsequent treatment with MeNH2 affords secondary N-alkyl-N-allyl
