An efficient Cu(acac)2-catalyzed oxidation of ketohydrazones afforded the corresponding α-diazeketones or ketazines in high yields depending on the reaction conditions. However, the reaction of benzophenone hydrazone gave benzophenone azine without affording diphenyldiazomethane. The formation of azines is explained by intermediacy of carbenoid generated by the Cu(acac)2-catalyzed decomposition of diazo compounds.

Reaction of azibenzils 1a - e with nonafluorosulfonebutanesulfonic anhydride (Nf2O) yields mainly vinylene bis(nonofluorobutanesulfonates) E,Z-2a - e and benzils 3a - e.The presence of a non-nucleophilic amine prevents decomposition of the azibenzils by traces of acid in the anhydride.Compounds 2 stem from an initial O-sulfonylation of the azibenzils, whereas C-sulfonylation perhaps leads to the benzils.Diazodiphenylmethane is decomposed by Nf2O to give tetraphenylethylene, benzophenone, and benzophenone azine.
