Nitrene addition to alkenes is a well-established method for the synthesis of aziridines. Photolysis or thermolysis of organic azides are good ways to generate nitrenes. Nitrenes can also be prepared in situ from iodosobenzene diacetate and sulfonamides , or the ethoxycarbonylnitrene from the N -sulfonyloxy precursor.
Its derivatives, also referred to as aziridines, are of broader interest in medicinal chemistry. Structure. The bond angles in aziridine are approximately 60°, ...
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.

The Blum–Ittah aziridine synthesis, also known as the Blum–Ittah-Shahak aziridine synthesis [1] or simply the Blum aziridine synthesis is a name reaction of organic chemistry, for the generation of aziridines from oxiranes.
The 5-membered ring compounds containing two heteroatoms, at least one of which is nitrogen, are collectively called the azoles. Thiazoles and isothiazoles contain a sulfur and a nitrogen atom in the ring. Dithioles have two sulfur atoms. A large group of 5-membered ring compounds with three or more heteroatoms also exists.

2H-Azirine is most often obtained by the thermolysis of vinyl azides. [2] During this reaction, a nitrene is formed as an intermediate. Alternatively, they can be obtained by oxidation of the corresponding aziridine.
