The oxidation of anthracene in acetic acid with air in the presence of small proportion of nitric acid produced high quality anthraquinone with acceptable yields.A possible mechanism is suggested which explains the predominance of the oxidation reaction compared with that of nitration.

The reaction of hexanitroethane with dienes gave the Diels-Alder adducts of tetranitroethylene.Thus, the reaction in refluxing benzene of hexanitroethane with anthracene gave 11,11,12,12-tetranitro-9,10-dihydro-9,10-ethanoanthracene.Similarly, 9-methylanthracene and 9,10-dimethylanthracene gave 9-methyl-11,11,12,12-tetranitro-9,10-dihydro-9,10-ethanoanthracene and 9,10-dimethyl-11,11,12,12-tetranitro-9,10-dihydro-9,10-ethanoanthracene, respectively.Cyclopentadiene reacted with hexanitroethane in methylene chloride at -10 deg C to give 5,5,6,6-tetranitro-2-norbornene.Reaction of the anthracene adduct of tetranitroethylene with sodium iodide gave the sodium salt of 12-nitro-9,10-dihydro-9,10-ethanoanthracen-11-one, which was protonated with acetic acid to give the corresponding nitro ketone.Treatment of the sodium salt with clorine and bromine gave 12-chloro-12-nitro-9,10-dihydro-9,10-ethanoanthracen-11-one and 12-bromo-12-nitro-9,10-dihydro-9,10-ethanoanthracen-11-one, respectively.

The present invention relates to a process for preparing a nitrated compound, comprising the step of reacting a compound (A) comprising at least one substituted or unsubstituted aromatic or heteroaromatic ring, wherein said heteroaromatic ring comprises at least one heteroatom selected from the group consisting of oxygen, sulfur, phosphor, selenium and nitrogen, with a compound of formula (I) wherein Y is selected from the group consisting of hydrogen and nitro.

1-Sulfopyridinium nitrate was synthesized as a potent nitrating agent for the nitration of arenes without the need for any co-catalysts. A variety of nitro compounds were synthesized and fully characterized by IR, 1H NMR, 13C NMR, thermal gravimetric analysis (TGA), differential thermal gravimetry (DTG), CHN analysis and mass spectroscopy. Mechanistically, in situ generated nitrogen dioxide as a radical from the reagent is proposed for the presented nitration protocol.
Phosphoric acid modified montmorillonite clay: A new heterogeneous catalyst for nitration of arenes
Bharadwaj, Saitanya K.,Boruah, Purna K.,Gogoi, Pradip K.
, p. 124 - 128 (2014/12/11)
The easily available montmorillonite clay is treated with phosphoric acid and 10 wt.% is found to be the optimum concentration of phosphoric acid that can be adsorbed chemically on the surface of the clay. Acidity of this phosphoric acid treated montmorillonite clay (PAM) is determined by volumetric as well as potentiometric titration and characterized. Catalytic efficacy of PAM in nitration of various aromatic compounds is reported.
