Hyper-Rayleigh scattering (HRS) from liquid nitrobenzene was measured for several combinations of linear polarized incident and scattered light, for a range of scattering angles near 90 degrees . The observations show that the HRS intensity is dominated by the polar transverse collective mode contribution, and support a model where the long range dipole-dipole orientation correlations in a pola...

Nitrobenzene (NB) is toxic even at low concentrations and hence its contamination in the environment a pervasive concern. The electrochemical techniques have emerged as rosy method to sense degrade NB graphitic carbon nitride (g-C3N4) catalysts are found be promising for this. In this study, silver nanoparticles (AgNPs)-decorated n-[3-(trimethoxysilyl)propyl]ethylenediamine (EDAS)-modified nano...

In the title compound, C(14)H(13)N(3)O(3), the pyrazoline ring assumes an envelope conformation with the furanyl-bearing C atom at the flap position. The dihedral angle between the furan and nitrobenzene rings is 84.40 (9)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

Benzene, halobenzenes, and a number of more or less deactivated arenes,including nitrobenzene, readily reacted in anhydrous HIO3/AcOH/Ac2O/conc. H2SO4 mixtures to probably give ArIO2 intermediates or other hypervalent species (not isolated). The final reaction mixtures were poured into excess aq. Na2SO3 solution (a reductant) to give the purified iodinated products in 39-83% yields.

Xenobiotic reductase A (XenA) has broad catalytic activity and reduces various α,β-unsaturated and nitro compounds with moderate to excellent stereoselectivity. Single mutants C25G and C25V are able to reduce nitrobenzene, a non-active substrate for the wild type, to produce aniline. Total turnover is dominated by chemical rather than thermal instability.
