Regiospecific nitration of quinoline and isoquinoline was achieved via the Reissert compounds by treatment with acetyl nitrate. Nitration of 1-benzoyl-2-cyanoquinoline (3) afforded the 3-nitro derivative, which was converted to 3-nitroquinoline by hydrolysis with concentrated HCl. Meanwhile, 2-benzoyl-1-cyano-1,2-dihydroisoquinoline (4) was converted ultimately into 4-nitroisequinoline-1-carboxylic acid (10) via 4-nitro-1-cyanoisoquinoline by the same procedure. A novel method for introducing a nitro group at the β-position of a heterocyclic moiety has thus been developed. Crystal structure determinations and molecular orbital calculations of the Reissert compounds, are consistent with the regiospecific nitration.

Aromatic nitro compounds are extensively used in synthetic chemistry. We disclose a new approach to obtain nitroarenes regioselectively starting from carboxylic acids under acid-free reaction conditions.

Paragraph 0079; 0080, (2018/09/11)
The invention discloses a mechanical force under the action of the nitration of aromatic compounds of nitrate method. The invention provides a method for preparing aromatic nitro compounds, comprising the following steps: under the action of mechanical force, aromatic compound with a metal nitrate or its hydrate by the nitration reaction, to obtain the aromatic nitro compound; the mechanical fastener is machinery offers can cause material physical and/or chemical nature of the change of the external force. The mechanical force can be compression, shear, impact, friction, tensile, bending and vibration of any kind. The invention has the following advantages: without the use of any solvent, thereby avoiding the waste liquid produced; and without the use of the acidic substance, the reaction is complete after treatment is simple, without any damage to the apparatus; a very high conversion and selectivity, can be applied to the nitration of conventional aromatic compound.
