The Suzuki-Miyaura reaction (SMR), involving the coupling of an organoboron reagent and an organic halide or pseudo-halide in the presence of a palladium or nickel catalyst and a base, has arguably become one of most utilized tools for the construction of a C-C bond. This review intends to be general account of all types of catalytic systems, new coupling partners and applications, including th...

Ni(PMe3)4 serves as a catalyst for the release of H2 and CO2 from formic acid. The capacity of Ni(PMe3)4 to achieve this transformation is linked to the ability of the PMe3 ligand to induce decarboxylation, as illustrated by the observation that both Ni(py)4(O2CH)2 and Ni(O2CH)2·2H2O react with PMe3 to afford Ni(PMe3)4; the latter transformation also provides a convenient method for the synthes...

The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...

Copper (Cu) is the most potent catalyst for dioxin formation, but Iron (Fe), Zinc (Zn), Potassium (K) and Sodium (Na) have also been found in multiple studies to be correlated with increased dioxin/furan formation. Some studies have also indicated that Manganese (Mn), Magnesium (Mg) and Nickel (Ni) may also serve as catalysts for dioxin formation. Studies have conflicted on whether Aluminum (Al...

This highlight discusses developments in transition metal-catalysed alkene and alkyne hydroacylation reactions over the past three years. The discussion summarizes the development of new catalyst systems for alkene and alkyne hydroacylation and applications to the synthesis of important ketone building blocks. The highlight captures transition metal-catalysed alkene and alkyne hydroacylation at...

Steam reforming is one of the most important processes for producing hydrogen from hydrocarbon fuels such as LPG and has attracted much attention due to its high efficiency and economy. In this study, the LPG steam reforming reaction was investigated on nickel catalysts supported on four various zeolites (H-Y, Na-Y, HZSM5 and Ferrierite). The catalytic tests were performed in a tubular fixed be...

Abstract Nickel and lanthanum on MgO or MgO–Al 2 O 3 catalysts were prepared characterized. The applicability of the was studied in liquid-phase hydrogenation benzonitrile. A La/MgO catalyst showed surprisingly high activity selectivity. scope reaction extended to other nitriles (benzyl cyanide, cinnamonitrile, adiponitrile) over this catalyst.

A general protocol for the selective hydrogenation and deuteration of a variety alkenes is presented. Key to success these reactions use specific nickel-graphitic shell-based core–shell-structured catalyst, which conveniently prepared by impregnation subsequent calcination nickel nitrate on carbon at 450 °C under argon. Applying this nanostructured both terminal internal alkenes, are industrial...

Abstract Nickel boride catalyst prepared in situ from NiCl2 and sodium borohydride allowed, the presence of an aqueous solution TEMPO-oxidized nanocellulose (0.01 wt%), reduction a wide range nitroarenes aliphatic nitro compounds. Here we describe how modified has stabilizing effect on that enables low loading nickel salt pre-catalyst. Ni-B methanolic was also used to develop greener facile org...
