Nitrosohydroxylamine derivatives

Insertion of isocyanides R NC (R = MesC or MesSi), which are isoelectronic to CO, appears to be quite similar (Scheme 10) this step has been used to achieve overall hydrocyanation (see Section 3.9.3.4.3). C—S and C—N bonds may also be generated. SO2 inserts with retention of configuration to yield [Cp2ClZr02SR], while NO leads to A(-nitrosohydroxylamine derivatives [Cp2ClZrj ON(NO)R) ]. Neither of the last two has been exploited synthetically. 

Grignard reagents have reacted with diimide dioxides prepared from nitrosohydroxylamines and with toluenesulfonyl derivatives of nitroso-hydroxylamines to prepare unsymmetrical azoxy compounds, including aliphatic-aromatic types. 

A study33 has been made of the rearrangement of /V-triarylmethylanilines to their p-triarylmethyl derivatives. A-Methyl-A-nitrosoaniline has been observed to undergo a Fischer-Hepp rearrangement when treated with montmorillonite clay,34 and /V-aryl-A-nitrosohydroxylamine ammonium salts (30) have been transformed35 into azoxy...

Odm Processes - The benzophenone sensitised reaction of the N,0-diacyl N-phenylhydroxylamine (189) in hexadecyltrimethylanunonium chloride micelles yields benzoyloxy-migrated products (190) and (191) derived from amidyl-benzoyloxyl radical pairs located at the micellar surface, whereas amidyl-phenyl radical pairs that penetrate more deeply into the micelle are responsible for phenyl-migrated products (192) and (193). Irradiation of ethanolic solutions of N-aryl-N-nitrosohydroxylamine ammonium salts produces azoxy compounds. 

Oxidized nitrogen. Aqueous 80s absorbs NO and forms [803N202] , i.e., A-nitrosohydroxylamine-A-sulfonate, a hyponitrite derivative ...
