3 H -diazirine |
3,3-dimethyl-diazirine |
Diazirines are heterocyclic organic chemical substances that contain a three-membered ring consisting of two nitrogen atoms and one carbon atom, with the two nitrogen atoms forming an azo group (-N = N-). The diazirines belong to the larger group of three-ring compounds with two heteroatoms in the ring.
synthesis
Diazirines can be prepared from a corresponding amidine by the Graham reaction . Alternatively, the oxidation of a diaziridine also produces a diazirine:
Silver oxide (Ag 2 O) can also be used as an oxidizing agent .
properties
Diazirines break down into radical carbenes and elemental nitrogen after exposure to ultraviolet light . Pure diazirines can explode with the elimination of nitrogen:
Diazirines are used in biochemistry for photoaffinity labeling .
