α-Oxophosphonium ylides (3a-3e) react with N-chlorosuccinimide and N- bromosuccinimide in the presence of azidotrimethylsilane giving the corresponding haloazidoalkenes (4a-4g) with elimination of triphenylphosphine oxide. These compounds were completely convened to the 2H-azirines 5a-5g on heating in heptane.
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.
