Interestingly, the final catalytic product is strongly dependent on the nature of the hydrogen donor source. 17 0 obj The amino group provides unique reactivity which makes it an … Pd nanoparticles with a mean diameter of 2.2 nm on amine-functionalized UiO-66 were synthesized by facile anionic-exchange followed by chemical reduction. You’ve supercharged your research process with ACS and Mendeley! The yield of nitrobenzene reduction to aniline increased from 20% to an almost quantitative yield over a range of alcohols, diols and aminoalcohols. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The catalysts exhibits a higher selectivity to aniline, with low accumulation of intermediate products. RAMAIAH INSTITUTE OF TECHNOLOGY, BANGALORE INTRODUCTION Aniline is an organic compound consisting of a phenyl group attached to an amino group, where aniline is the prototypical aromatic amine.

The maximum conversions were reached after 80 min at 293 K and 303 K (Fig. without permission from the American Chemical Society. , adsc202000127-sup-0001-misc_information.pdf. redistribute this material, requesters must process their own requests via the RightsLink permission Number of times cited according to CrossRef: An Efficient and Robust Method for Selective Conversion of Aniline to Azobenzene Using nano‐TiO Please reconnect. Epub 2007 Feb 15. In ethanolamine, the reaction was conveniently performed at a lower temperature (55 °C) and gave selectively substituted azobenzene (92% yield). The high chemoselectivity of both protocols has been proved in experiments on a panel of variously substituted nitroarenes. 16 0 obj  |  Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, I have read and accept the Wiley Online Library Terms and Conditions of Use.

Highly Selective Synthesis of Hydrazoarenes from Nitroarenes via Polystyrene-Supported Au-Nanoparticle-Catalyzed Reduction: Application to Azoarenes, Aminoarenes, and 4,4'-Diaminobiaryls. Consequently, a 0.25 wt % Pt catalyst, supported on Na-containing CeO2 nanorods and reduced at 600 °C, displays a high level of aniline productivity of 40.8 molAN/gPt/h and excellent stability in nitrobenzene hydrogenation at room temperature. The kinetic study displayed orders 1 respect to hydrogen pressure and to the substrate concentration (nitrobenzene), and the activation energy was 67.2 KJ/mol.
