Synthesis and Facile Dearomatization of Highly Electrophilic Nitroisoxazolo[4,3-b]pyridines
Molecules, 2020 A number of novel 6-R-isoxazolo[4,3-b]pyridines were synthesized and their reactions with neutral C-nucleophiles (1,3-dicarbonyl compounds, π-excessive (het)arenes, dienes) were studied.

Nitrification Progress of Nitrogen-Rich Heterocyclic Energetic Compounds: A Review
Molecules, 2022 As a momentous energetic group, a nitro group widely exists in high-energy-density materials (HEDMs), such as trinitrotoluene (TNT), 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), cyclo-1,3,5-trimethylene-2,4,6-trinitramine (RDX), etc.

N-(4-Ethoxy-2,5-dinitrophenyl)acetamide
IUCrData, 2020 In the title compound, C10H11N3O6, the torsion angles about the bonds to the benzene ring are less than 4°, except for the nitro groups, which are twisted out of the ring plane by 25.27 (3) and 43.63 (2)°.

Cathodic hydrodimerization of nitroolefins
Beilstein Journal of Organic Chemistry, 2015 Nitroalkenes are easily accessible in high variety by condensation of aldehydes with aliphatic nitroalkanes. They belong to the group of activated alkenes that can be hydrodimerized by cathodic reduction.

Acta Crystallographica Section E: Crystallographic Communications, 2019 The title compounds, both C8H4F3NO4, represent two isomers of nitro trifluoromethyl benzoic acid. The compounds each contain a nitro functionality para to the carboxylic acid group, with the trifluoromethyl substituent ortho to the acid group in the 2 ...

Structure of the Nitro Group [PDF]
Nature, 1934 THE usual formula given to the nitro group is containing a co-ordinate link1, and it is sup-ported by the parachor evidence2. On account of this dissymmetry, both the compounds 1-4-dinitrobenzene and 1-3-5-trinitrobenzene should possess finite electric dipole moments.

N-(4-Methoxy-3-nitrophenyl)acetamide
IUCrData, 2023 The title compound, C9H10N2O4, crystallizes with a disordered nitro group in twinned crystals. Both the methoxy group and the acetamide groups are nearly coplanar with the phenyl ring, and the C—N—C—O torsion angle [0.2 (4)°] is also insignificantly ...
