چکیده

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 Preconcentration and Determination of Pb2+, Cu2+, Co2+, Ni2+, Fe2+ and Zn2+ Elements in Water Samples Using Citrate Form of Anion-Exchange Resin

Lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. These are subsequently recovered from the resin by 0.5M ammonium citrate eluent at pH 2.0. Under optimized conditions, quantitative recovery ...

β-Hydrogen Elimination Reactions of Nickel and Palladium Methoxides Stabilised by PCP Pincer Ligands.

Nickel and palladium methoxides [((iPr)PCP)M-OMe], which contain the (iPr)PCP pincer ligand, decompose upon heating to give products of different kinds. The palladium derivative cleanly gives the dimeric Pd(0) complex [Pd(μ-(iPr)PCHP)]2 ((iPr)PCHP = 2,6-bis(diisopropylphosphinomethyl)phenyl) and formaldehyde. In contrast, decomposition of [((iPr)PCP)Ni-OMe] affords polynuclear carbonyl phosphin...

Spectrophotometric Study of Cobalt, Nickel, Copper, Zinc and Lead Complexes with Methylthymol Blue in Binary Water-Methanol Mixtures

The complexation reactions between methylthymol blue (MTB) and Co2+, Ni2+, Cu2+, Zn2+ and Pb2+ ions have been studied in different water-methanol mixtures at pH 4.45 and 25 °C by a spectrophotometric technique. The stepwise stability constants of the resulting 1:1 and 2:1 (metal ion to ligand) complexes were determined from the absorban...

Electrocatalytic CO2 reduction with nickel complexes supported by tunable bipyridyl-N-heterocyclic carbene donors: understanding redox-active macrocycles.

A series of nickel complexes featuring redox-active macrocycles is reported for electrocatalytic CO2 reduction. A remarkable structure-activity relationship is elucidated from the series through electrochemical studies and DFT calculations, wherein a fine electronic balance between metal and ligand redox chemistry dictates selectivity for CO2 reduction versus the competing proton reduction reac...

Effect of K2O on the catalytic performance of Ni catalysts supported on nanocrystalline Al2O3 in CO2 reforming of methane

CO2 reforming of methane (CRM) over unpromoted and potassium promoted Ni/Al2O3 catalysts was studied. The catalysts were prepared by impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption (BET), temperature programmed reduction (TPR), temperature programmed oxidation (TPO) and scanning electron microscope (SEM) techniques. The obtained results showed that addition of K2...
