Nitration with nitrogen dioxide alone

NITRATION WITH NITROGEN DIOXIDE ALONE Aromatic compounds 

When nitrating anthracene with N204 at a temperature of 10-15°C Liebermann and Lindermann [53] obtained nitro derivatives of this hydrocarbon. 

Meisenheimer s observation [54], in 1904, that anthracene combined with nitrogen dioxide to form meso-dihydrodinitroanthracene, was of special importance  

It inspired Wieland [55] in 1921 to investigate the possibility of nitrating aromatic compounds with nitrogen dioxide. 

As a result of nitrating phenol by means of N204 at a low temperature, a mixture of o- and p- nitrophenol was obtained.

Reaction of benzanthrone with nitrogen dioxide alone or in admixture with ozone gives a mixture of nitrated products including 3-nitrobenzanthrone, which is a new class of powerful direct-acting mutagens of atmospheric origin (Eq. 2.12).26... 

In this metho d [ 124 ] nitrate, nitrate plus nitrite or nitrite alone are selectively reduced to nitric oxide, which is swept from the sample in a helium carrier gas flow. Nitric oxide is allowed to react with ozone in a nitrogen oxide analyser, where it forms nitrogen dioxide. The return of the nitrogen dioxide to the ground state is accompanied by release of a photon, which is detected by a photomultiplier. The integrated output of the photomultiplier over the time that the nitric oxide is pinged from the sample is proportional to the nitrite content of the sample.
