Imidazolium-based poly(ionic liquids) with hydroxide as the counter anion were employed to prepare stable aqueous dispersion of Ni nanoparticles. The synthesized poly(ionic liquid) stabilized Ni nanoparticles (PIL-Ni-NPs) were characterized by thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM), powder XRD, TEM, Brunauer-Emmett-Teller (BET) surface area measurements, X-ray photoelectron spectroscopy (XPS), EPR, and UV/Vis spectroscopy. The PIL-Ni-NPs possess good catalytic activity towards transfer hydrogenation (TH) reactions of carbonyl compounds to their alcohol derivatives, in isopropanol at 80 °C in the absence of any additional base. This catalyst system chemoselectively reduces only the carbonyl group of α,β unsaturated carbonyl compounds. The magnetically separable PIL-Ni-NPs were recycled and reused for further TH reactions. © 2016 Wiley-VCH Verlag GmbH &amp; Co. KGaA, Weinheim.

Ni Nanoparticles Stabilized by Poly(Ionic Liquids) as Chemoselective and Magnetically Recoverable Catalysts for Transfer Hydrogenation Reactions of Carbonyl Compounds

Oxidation reactions are significant transformations used extensively in chemical production. Use of molecular oxygen as an oxidant is certainly environmental friendly and adds to the greenness of the process. A number of metal catalysts have been developed for aerobic oxidation. This digest summarizes the recent advances in aerobic oxidation reactions using ruthenium catalysts for various transformations such as C–H activation/cyclization, alkyne/alkene oxidation, and oxidation of alcohols and amines. © 2016 Elsevier Ltd

Ruthenium-functionalized nickel hydroxide catalyst for highly efficient alcohol oxidations in the presence of molecular oxygen

Nafion ionomer anchored ruthenium oxide pyrochlore composite has been demonstrated for selective oxidation of alcohols to aldehydes and ketones in good yields. In the absence of any additives, the reaction was achieved by atmospheric air or molecular oxygen at room temperature. © 2008 Elsevier Ltd. All rights reserved.
