A new family of low-coordinate nickel imides supported by 1,2-bis(di-tert-butylphosphino)ethane was synthesized. Oxidation of nickel(II) complexes led to the formation of both aryl- and alkyl-substituted nickel(III)-imides, and examples of both types have been isolated and fully characterized. The aryl substituent that proved most useful in stabilizing the Ni(III)-imide moiety was the bulky 2,6...

ABSTRACT Infrared spectroscopy has been employed for a detailed characterization of ZrO2 and CeO2/ZrO2 supported nickel and copper/nickel catalysts to be utilized for methane decomposition. Adsorption of CO at 303 K was performed in order to determine the surface composition and accessible adsorption sites. Alloy formation occurred during reduction, as indicated by a red-shift of the vibrationa...

The reactions of PCP supported Ni hydride, methyl and allyl species with CO(2) to generate Ni carboxylates are described. Computational studies suggest that all three reactions follow different pathways.

The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...

Green is the future of chemistry. Catalysts with high selectivity are the key to green chemistry. Polymer-supported Raney catalysts have been found to have outstanding performance in the clean preparation of some chemicals. For example, a polyamide 6-supported Raney nickel catalyst provided a 100.0% conversion of n-butyraldehyde without producing any detectable n-butyl ether, the main byproduct...

In this workN2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide (DPD), was synthesized via reaction of 2-aminothiazole and 2,6- pyridinedicarboxylic acid in n-methylpyrrolidine. The obtained (DPD) was characterized with nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FT-IR) spectroscopy, and elemental analysis. Finally, a novel magnetic nanoadsorbent was synthesized by m...
