Synthesis and reactivity of 2-halo-2H-azirines towards nucleophiles

Nucleophilic substitution reactions of 2-halo-2H-azirine with potassium phthalimide and aniline allowed the preparation of new substituted 2H-azirines. The reactions of 2-bromo-3-phenyl-2H-azirine-2-carboxylate with methylamine led to the synthesis of α-diimines and from the reaction with water, a 3-oxazoline was obtained.
