Aziridine is an organic compound consisting of the three-membered heterocycle C 2 H 5 N. [ 5 ] [ 6 ] It is a colorless, toxic, volatile liquid that is of significant practical interest. [ 7 ] Aziridine was discovered in 1888 by the chemist Siegmund Gabriel . [ 8 ]
Mitomycin C, an aziridine, is used as a chemotherapeutic agent by virtue of its antitumour activity. [1]In organic chemistry, aziridines are organic compounds containing the aziridine functional group (chemical structure (R−) 4 C 2 N−R), a three-membered heterocycle with one amine (>NR) and two methylene bridges (>CR 2).
Aziridiniums are the ionic form of the class of molecules known as aziridines. [1] Aziridines can be used to insert nitrogen atoms during synthesis, but without any substituents attached to the nitrogen in the ring, they are considered nonactivated and inert. [2] They can be rendered active by the preparation of aziridinium ions.
Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH 2 CH 2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups.

Polyethylenimine is a polymer derived from aziridine. Other synthetic polyamines include 1,3,5-triazinane (not to be confused with 1,3,5-triazine) and N-substituted analogs. The methylene (−CH 2) linkages are derived from formaldehyde.
Alternatively, they can be obtained by oxidation of the corresponding aziridine. Azirine can be generated during photolysis of isoxazole. [ 3 ] Due to the weak N-O bond, the isoxazole ring tends to collapse under UV irradiation, rearranging to azirine.
