Astolfi, Paola published the artcileReactions of nitrosoarenes with nitrogen monoxide (nitric oxide) and nitrogen dioxide: formation of diaryl nitroxides, COA of Formula: C12H9N3O4, the publication is European Journal of Organic Chemistry (2008), 3279-3285, database is CAplus.
Nitrosoarenes react. with nitrogen monoxide (nitric oxide) at room temperature and in aprotic media to afford the corresponding diaryl nitroxides by the intermediate formation of N-nitrosoaryl nitroxides. However, these latter spin adducts, in contrast with literature reports, have never been detected by us. N-nitrosophenyl nitroxide is obtained only in the oxidation of the ammonium salt of N-nitrosophenylhydroxylamine (cupferron) with trace amounts of lead tetraacetate. However, it evolves with time to di-Ph nitroxide, as demonstrated by following the reaction course in the ESR cavity. On a macroscale level, the reaction between nitrosobenzene and nitric oxide gives N-nitrosodiphenylamine, 4-nitro-N-nitrosodiphenylamine, 4-nitrodiphenylamine and 4,4′-dinitrodiphenylamine, in addition to di-Ph nitroxide. Diaryl nitroxides are also obtained when nitrosoarenes react with small amounts of nitrogen dioxide; the mechanism of this reaction is proposed and discussed. The structure of 4-nitro-N-nitrosodiphenylamine was determined by x-ray anal.
