Reactions of Nitrenes with Nucleophiles

7-Azido-nitrobenzoxadiazole (azido-NBD) was observed to undergo a reduction reaction in the absence of an obvious reducing agent, leading to amine formation. In 

Sulfonimidamides lead efficiently to nitrenes and have been converted into sulfimides, sulfoximines, and aziridines in good yields through a copper-mediated 

The diatomic molecule N H and its derivatives R-N are usually referred to as nitrenes, with six electrons on the nitrogen. 

Nitrenes are monovalent nitrogen species, and are isoelectronic with carbenes. Nitrenes like carbenes are immensely reactive and electrophihc. 

The chemistry of nitrenes closely parallels that of carbenes in virtually aU aspects. Like carbenes there is the possibility of two spin states for nitrenes, depending on whether the two nonbonding electrons have their spins paired or parallel.
