D.; Tetrahedron 1962, 17, 31. 2 The nitrosobenzene formation is catalyzed by functionalized multiwalled carbon nanotubes (CNT) followed by a coupling reaction between nitrosobenzene and aniline to produce azobenzene. This pathway remains the most common for aniline production today. The results clearly demonstrate that this oxidation system is more efficient than Ishii system in the selective oxidation of aniline with hydrogen peroxide.26. Enhanced photocatalytic activities of commercial P25 TiO 2 by trapping holes and transferring electrons for CO 2 conversion and 2,4-dichlorophenol degradation. As in previous studies, a two‐step process with a first step of attack of aniline on nitrosobenzene to give an addition intermediate and a second step of dehydration of this intermediate is proposed to interpret the mechanism of the reaction.

Elevation of reaction temperature has no effect on the selectivity of aniline oxidation with H3PW12O40 as catalyst.

Direct asymmetric N-specific reaction of nitrosobenzene with aldehydes catalyzed by a chiral primary amine-based organocatalyst Chirality. Chem. The catalytic activity of H3PMo12O40 is much less than H3PW12O40. Str. NaYF Yadav, G. D.; Pujari, A. Aniline was first commercially produced using nitrobenzene as starting material in 1930s. It is well known that heteropolyoxometalates catalyze homogeneous oxidation of a wide range of organic compounds such as olefins,6,7,8 thioethers, 6 and alcohols7 with several terminal oxidants such as alkyl hydroperoxide,9 molecular oxygen,10 iodosyl benzene,8 as well as hydrogen peroxide.11, Oxidation of amines to their corresponding oxygen-containing derivatives has attracted much attention during the past few decades.12 Azobenzene,13,14 azoxybenzene,15,16 nitrobenzene17,18 and nitrosobenzene,19-21 have been formed in the oxidation of aniline by organic22 and inorganic23 oxidants. Other Mo- and W- substituted polyoxometalates showed lower activity. Visible light irradiation (λ > 450 nm) of Pt nanoparticles supported on Degussa P25 TiO2 (Pt/P25 catalyst) promotes efficient and selective aerobic oxidation of aniline to nitrosobenzene. Antioxid Redox Signal. 2011 Aug;23(7):527-33. doi: 10.1002/chir.20960.
