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.
