Nitrenes aminonitrenes

Aminonitrene (isodiazene) (145) is the least stable of all isomers of the elemental composition N2H2 and was isolated in an argon matrix for the first time in 1984.195 Theoreticians also gave much attention to aminonitrene (145).196 This molecule is exceptional in so far, that it is one of the few nitrenes with a singlet electronic ground state and is best described by the dipolar structure 145. ... [Pg.148]

Oxygen substituted nitrenes have received much less study than aminonitrenes, but there have been some noteworthy recent developments. Toscano and co-workers " studied the photochemistry of diazenium diolates. The quantum yield of photodegradation was 0.10. [Pg.547]

R = acyl groups. As discussed on p. 202, singlet nitrenes add stereospecifically while triplet nitrenes do not. Diphenyl sulfimide Ph2SNH converts Michael-type substrates to the corresponding aziridines.813 Aminonitrenes R2NN have been shown to add to triple bonds to... [Pg.834]

The aminonitrenes have much in common with the five-membered aromatic nitrenes, but are a class apart due to strong resonance stabilization of the 1,1-diazene form. General reviews on aminonitrenes are available.390-392... [Pg.343]
