C-Nitroso compounds with hydroxylamines

One of the reactions which has been used to prepare azoxy compounds is the condensation of C-nitroso compounds with hydroxylamines. In the aliphatic series this reaction is quite general and permits the preparation of unsym-metrical azoxy compounds. In the case of aromatic compounds, however, only symmetrical azoxy compounds can be synthesized reliably. In the reaction of dissimilar aromatic nitroso compounds and aromatic hydroxylamines, a complex mixture of azoxy products is obtained. 

It is self-evident that one of the simpler methods of preparing unsymmetrically substituted azoxy compounds must involve the condensation of two distinctly different starting materials. In principle, the reaction of C-nitroso compounds with hydroxylamines meets this requirement (Eq. 1).
