2,4-Dinitrophenylhydroxylamine (1) is an efficient reagent for the iron-catalyzed regioselective allylic amination 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
2,4-二硝基苯基羟胺 (1) 是铁催化烯烃区域选择性烯丙基胺化的有效试剂。由于在较少取代的乙烯基碳上引入 N-DNP 基团并伴随双键转位,获得了中等至极好的 N-DNP-N-烯丙基胺 (2) 产率。2的N-烷基化和随后用MeNH 2 处理以良好的总产率提供仲N-烷基-N-烯丙基胺(5)。
