We hereby present our results in the selective and fast oxidation of aniline by hydrogen peroxide in the presence of several simple heteropolyoxometalates at room temperature under simple reaction conditions. (redox) Preparing steps of aniline from nitrobenzene Nitrobenzene is reduced to aniline salt by Sn / concentrated HCl. :Yb. NIH Nitrosobenzene is widely used as an intermediate in the synthesis of azomethine derivative, allylamines and oxazines , , , . 2 In summary, we have shown that the oxidation of aniline by 35% hydrogen peroxide, catalyzed by H3PW12O40 family (under two-phase conditions at room temperature or under reflux) provides a simple and general procedure for the preparation of nitrosoaniline, that is difficult to prepare selectively by conventional methods. General procedure for oxidation of aniline to nitrosobenzene, To a stirred solution of catalyst (0.015 mmol), n equivalents of CPC (n= charge on polyanion) if present, and 30%H2O2(8 mmol) in CH2Cl2(7 mL) was added aniline (4 mmol), and the mixture was stirred at room temperature for the required time. Table 1 introduces the results of aniline oxidation into nitrosobenzene as the major product and nitrobenzene as the minor product. 2 New insight into the selective photocatalytic oxidation of RhB through a strategy of modulating radical generation.

H, under Visible Light Irradiation. the Altmetric Attention Score and how the score is calculated. Aniline, also known as amino benzene or benzenamine, is an aromatic amine with the formula C6H5NH2. NaYF Baumgarten, H. E.; Staklis, A.; Miller, E. M.; J. Org. Visible-Light Photocatalytic Degradation of Aniline Blue by Stainless-Steel Foam Coated with TiO2 Grafted with Anthocyanins from a Maqui-Blackberry System. Nitrobenzene is reduced to aniline by Sn and concentrated HCl. Near-field dielectric scattering promotes optical absorption by platinum nanoparticles.,,,,,,,,,,,,,,,,,,,,,,,,, The analysis of the Brønsted relationship and of the intermediate of the reaction led to the suggestion that hydoxide ion catalyses the reaction by a mechanism of general base catalysis in the dehydration step. The promoting role of bismuth for the enhanced photocatalytic oxidation of lignin on Pt-TiO2 under solar light illumination. Na3PW9Mo3O40 and K4SiW9Mo2O39 also displayed high reactivity in the oxygenation system.
