in which R1 is a radical containing one or more aromatic nuclei, the nitrogen atom is attached to a nuclear carbon atom of R1 and the two carbonyl groups are linked to adjacent nuclear carbon atoms in Ar, and where there is at least one fluorine atom as a nuclear substituent in Ar, R...
Nitroaromatic compounds=Nitrogen-containing organic compounds used worldwide as explosives, pesticides, and as precursors for the manufacture of many products, including dyes, pharmaceuticals, and plastics pathway (e.g., 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitrobenzene (TNB), dinitrotoluene ...
Residual (13C, 14N) dipolar coupling in 13C NMR of solid nitrogen‐containing aromatic compounds Carbon-13 NMR spectra of some solid substituted anilines and aromatic diazonium salts, taken under conditions of cross-polarization with high-power proton decoupling, are presented. In the case of ...
Heterocyclic aromatic compounds contain one or more rings with delocalised π-electrons along with at least one of the carbon atoms replaced by any heteroatom such as sulphur, oxygen, nitrogen etc. From:Dyes and Pigments,2023 About this page ...

with the low molecular weight aliphatics produced by sunlight, but driven by the photo-produced aromatics. This aromatic compound-driven acceleration of biodegradation may be attributed to the potential high abilities of the microbes to decompose complex compounds in thermokarst lakes. These findings ...
22.4.1.2Benzenoid and heterocyclic compounds A diverse range of 56aromatic compoundshave been reported,4which included mono-, di-, tri-, and tetra-substituted benzenoids, mono- and di-substitutedfurans, and nitrogen containing derivatives of pyridine,pyrrole, andindole. Most of these have only been...
