Nitrenes are nitrogen analogues of carbenes that contain no charge and are highly reactive and electrophilic. They exist in both singlet and triplet states, with the triplet state being more stable due to the presence of unpaired electrons. Nitrenes can be generated from acyl and alkyl azides, from sulphinylamine, or through insertion reactions. Important reactions involving nitrenes include the Beckmann rearrangement, Hofmann bromamide reaction, Curtius rearrangement, Lossen rearrangement, and Schmidt rearrangement.
