CHAPTER XXNITRONITROSO AND NITROSO COMPOUNDS
DINITRODINITROSOBENZENE
THE METHOD of the preparation of dinitrodinitrosobenzene has already been
discussed (see p. 263). This product also forms in the thermal decomposition of
picryl azide at temperatures of 90-100°C. In addition, nitrogen is generated in
the reaction (Rathsburg [I]):
More recent studies on the structure of o- dinitroso derivatives of benzene in-
dicate they may have the benzofurazan ring (I) which was described for the first
time by Forster and Fierz [2].
Green and Rowe [3] suggested a benzofuroxane structure (II) for o- dinitroso-
benzene and its derivatives. This view was further developed by Hammick,
