Formation and properties of Ziegler systems based on nickel bis(dimethylglyoximate) in catalysis of hydrogenation reactions

The effect of the nature of the acidoligand in the nickel precursor on the activity of Ziegler systems in hydrogenation of alkenes was characterized qualitatively. The key steps of the reaction of nickel bis (dimethylglyoximate) with triethylaluminum determined by the methods of IR, NMR, and ESR spectroscopy include the reaction between AlEt3 and the OH group of the dimethylglyoximate ligand, formation of the product of C-alkylation as a result of addition of AlEt3 to the C=N bond, and the reduction of Ni(II) to Ni(0) complexes. The absence of nickel clusters and a low concentration of coordinatively unsaturated Ni(0) complexes is the most probable reason of low catalytic activity of the studied system in hydrogenation catalysis.

Ferromagnetic S = 1 chain formed by a square Ni2S2 motif in Ni(qt)2 (qt = quinoline-8-thiolate). Magnetic properties of related compounds

ML2 complexes [M = Fe2+, Co2+, Ni2+, Cu2+; L = quinolin-8-olate (q), quinoline-8-thiolate (qt)] were prepared and their magnetic properties were studied. X-ray crystal structure analysis of Ni(qt)2 reveals that nickel(II) ions are arranged to form a one-dimensional structure with double thiolate bridges. Magnetic susceptibility measurements of Ni(qt)2 indicate that the nickel S = 1 spins are ferromagnetically coupled within a chain. Other ML2 showed antiferromagnetic interactions. Magnetic properties of molecular complexes of ML2 with 7,7,8,8-tetracynanoquinodimethane (TCNQ) were also investigated. The crystal structure of Ni(qt)2(TCNQ) was determined.

Rational design of marigold-shaped composite Ni3V2O8flowers: A promising catalyst for the oxygen evolution reaction

Advancement of double spinel-type blended metal oxides and designing heterostructured nanomaterials with assorted shapes using two different metals remains an active area of research. In this work, we designed marigold flower-shaped Ni3V2O8 structures by simple and facile thermal decay of Ni(ii) 8-hydroxyquinoline and VO(ii) 8-hydroxyquinoline molecular precursors using a universal and green solvent, water. The marigold flower-shaped structure of Ni3V2O8 was characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). Finally, we tested these marigold flower-shaped Ni3V2O8 structures for their electrochemical performance, such as the oxygen evolution reaction (OER). The results demonstrated that the marigold flower-shaped Ni3V2O8 structure has superior catalytic activity (overpotential of 328 mV at 10 mA cm-2 and a Tafel slope of 61 mV dec-1) compared with a physical mixture of V2O5 and NiO (overpotential of 496 mV at 10 mA cm-2 and a Tafel slope of 158 mV dec-1), pure NiO (overpotential of 553 mV at 10 mA cm-2 and a Tafel slope of 205 mV dec-1) or V2O5 (overpotential of 668 mV at 10 mA cm-2 and a Tafel slope of 314 mV dec-1) in alkaline medium. This higher OER activity of the marigold flower-shaped Ni3V2O8 structure strengthens its adoption as a potential candidate in the field of energy storage and conversion systems. This journal is

The possibility of polymerization of the nickel(II) complex with a pyridine-type ligand, i.e., 8-hydroxyquinoline (Hqol) was studied. It was found that poly[Ni(qol)2] possesses electrical conduction in a supporting electrolyte solution and photo and electrochemical activities. Nauka/Interperiodica 2006.

Design, synthesis, and antifungal evaluation of 8-hydroxyquinoline metal complexes against phytopathogenic fungi

Phytopathogenic fungal infections have become a major threat to agricultural production, food security, and human health globally, and novel antifungal agents with simple chemical scaffolds and high efficiency are needed. In this study, we designed and synthesized 38 8-hydroxyquinoline metal complexes and evaluated their antifungal activities. The results showed that most of the tested compounds possessed remarkable in vitro antifungal activity. Especially, compound 1e exhibited the highest antifungal potency among all target compounds, with EC50 values of 0.0940, 0.125, 2.95, and 5.96 μg/mL, respectively, against Sclerotinia sclerotiorum, Botrytis cinerea, Fusarium graminearum, and Magnaporthe oryzae. Preliminary mechanistic studies had shown that compound 1e might cause mycelial abnormalities of S. sclerotiorum, cell membrane permeability changes, leakage of cell contents, and inhibition of sclerotia formation and germination. Moreover, the results of in vivo antifungal activity of compound 1e against S. sclerotiorum showed that 1e possessed higher curative effects than that of the positive control azoxystrobin. Therefore, compound 1e is expected to be a novel leading structure for the development of new antifungal agents.
