A series of γ,δ-unsaturated azo compounds was prepared by thermal isomerization of allylalkylhydrazones obtained from the simplest carbonyl compounds. The oxidation of N-aminophthalimide with lead tetraacetate in the presence of these unsaturated compounds gave rise to mixtures of adducts at the azo group, regioisomers of phthalimidoazimines. The oxidative addition of N-aminophthalimide to 1-isopropylazocycloalkenes afforded bicyclic C-isopropylazo-N-phthalimidoaziridines, but the same reaction with 2-alkylazopropenes did not result in any adducts with these conjugated azocompounds.
通过对从最简单的羰基化合物中获得的烯丙基烷基肼进行热异构化,制备了一系列 γ、δ-不饱和偶氮化合物。在这些不饱和化合物存在的情况下,N-氨基邻苯二甲酰亚胺与四乙酸铅的氧化反应产生了偶氮基团上的加合物混合物,即邻苯二甲酰亚氨基嗪的regioisomers。将 N-氨基邻苯二甲酰亚胺与 1-异丙基偶氮环烯进行氧化加成,可得到双环 C-异丙基偶氮-N-邻苯二甲酰亚胺基氮丙啶,但与 2-烷基偶氮丙烯进行相同的反应却不会产生任何与这些共轭偶氮化合物的加合物。
