In the mol-ecule of the title compound, C(16)H(12)N(2)O(3), the nitrobenzene benzene ring forms a dihedral angle of 23.8 (8)° with the plane of the quinoline ring system. The crystal structure is stabilized by an aromatic π-π stacking inter-action between centrosymmetrically related benzene rings [centroid-centroid distance 3.663 (2) Å].
An efficient solvent free reaction of 1-chloro-2-nitrobenzene with anilines to give N-substituted nitro anilines by nucleophilic aromatic substitution in good to excellent yields has been described. The effect of different salts on the reaction has also been studied.
A novel biotin-guided anticancer drug delivery system, prodrug , consisting of biotin, nitrobenzene, and doxorubicin, with acid-triggered drug releasing capability was synthesized. Its cellular uptake and anticancer activity are selective to the HepG2 cell line over the WI-38 cell line, as revealed by fluorescence confocal microscopic experiments and MTT assay.
1-Fluoro-2,5-dimethoxy-4-nitrobenzene was synthesized in 90% yield by the reaction of commercial 2-fluoro-1,4-dimethoxybenzene with nitric acid. The structure was confirmed by X-ray crystallography. The new title compound was characterized by 1H and 13C-NMR, elemental analysis, EI-MS and FT-IR.
We report herein the first synthesis of propargylic alcohols using an organic reducing agent. Diarylbutynol derivatives are formed in moderate to good yields under mild conditions from the reaction of 1-(3-chloroprop-1-ynyl)-4-nitrobenzene with various aromatic aldehydes using tetrakis(dimethylamino)ethylene (TDAE) as reductant.
The theory and an implementation of the solvent contribution to the cubic response function for the polarizable continuum model for multiconfigurational self-consistent field wave functions is presented. The excited-state polarizability of benzene, para-nitroaniline, and nitrobenzene has been obtained from the double residue of the cubic response function calculated in the presence of an aceton...
beta-cyclodextrin can react with nitrobenzene to form an inclusion complex which is characterized by (1)H NMR and powder X-ray diffractometry. The ratio of beta-CD to NB in inclusion complex is determined as 1:1. At 25 degrees C, the dissociated constant, K(D), of the inclusion complex is measured as 6.5 x 10(-3) M in neutral solution (pH=7.0), but in alkali (pH=13.5), K(D) is 3.2 x 10(-2) M wh...
