diaziridine
Sign in to saveA diaziridine is a heterocyclic compound containing two nitrogen atoms in a three-membered ring. Diaziridines can be considered as strained hydrazines. Unlike most amine types of structures, the nitrogen atoms of diaziridines are configurationally stable because the ring strain prevents Walden inversion. As a result, there can be various stereoisomeric forms of this structure.

A diaziridine is a heterocyclic compound containing two nitrogen atoms in a three-membered ring. Diaziridines can be considered as strained hydrazines. Unlike most amine types of structures, the nitrogen atoms of diaziridines are configurationally stable because the ring strain prevents Walden inversion. As a result, there can be various stereoisomeric forms of this structure.
They are usually synthesized by treating a carbonyl compound with an aminating reagent like hydroxylamine-O-sulfonic acid and either ammonia or a primary aliphatic amine under slightly basic conditions. The final step is based on the intramolecular cyclization of an aminal.
