Deshmukh, Auteur ; Atul K. Prashar, Auteur ; Anil K. Kinage, Auteur Année de publication : 2011 Article en page(s) : pp. 12180–12184 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Catalyst Hydrogenation Résumé : Ru(II) Phenanthroline [Ru(II)(Phen)n where n = 1,2,3] complexes were used as highly chemoselective catalysts for hydrogenation of nitro aryls using molecular hydrogen in an aqueous media. Water, universal solvent, was used as a reaction mixture for hydrogenation of nitro-aryls to make the process green. The chemoselectivity in hydrogenation of substituted nitrobenzene to substituted aniline was obtained as high as >99% at about complete conversion of substituted nitrobenzene. The parametric effects, including effect of solvent, effect of ligand, effect of metal to ligand ratio, effect of temperature and pressure, were studied in detail to obtain the best results. The Ru(Phen)n was characterized by FTIR, UV−vis, and XPS.
