α-Oxophosphonium ylides react with N-chlorosuccinimide, N-bromosuccinimide and N-iodosuccinimide in the presence of azidotrimethylsilane giving the corresponding haloazidoalkenes which were completely converted to the 2-halo-2H-azirines on heating in heptane.

Eosin Y, a common organo-photocatalyst in visible-light photoredox processes, was found to show excellent catalytic activities for thermal redox reactions under a catalytic amount of Cu(OAc)2. With this catalytic system, vinyl azides and ketene silyl acetals combine to form formal [3 + 2] cycloadducts by α-ester radical addition without light irradiation. This method provides a mild and straightforward paradigm to prepare important synthons of five-membered ene-γ-lactams and bridge ring lactams. It is the first example of an eosin Y-catalyzed redox reaction in the dark.

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.
