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 & Co. KGaA, Weinheim.
