The utility of pincer−nickel complexes in catalyzing reactions such as cross−coupling, oxidation, (de)hydrogenation, hydrofunctionalization, C−H activation and CO<sub>2</sub> functionalization has been reviewed from a synthetic mechanistic point view.
A series of NNN pincer–ruthenium complexes the type (R2NNN)RuCl2(CH3CN) based on bis(imino)pyridine ligands were synthesized and characterized. These pincer ruthenium acetonitrile complexes, along with their phosphine carbonyl counterparts, tested for reforming methanol in water presence a base. The catalyst (Cy2NNN)RuCl2(PPh3) was found to be most efficient comparison other considered catalysts. Among bases screened, KOtBu (1.5 equiv respect water) give best results at temperatures as low...
The synthesis and characterization of a pincer-nickel complex the type (iPr2NNN)NiCl2(CH3CN) is reported here. We have demonstrated utility this (0.02 0.002 mol %) for catalytic N-alkylation amines using various alcohols. Under solvent-free conditions, while highest yield (ca. 90%) was obtained alkylation 2-aminopyridine with naphthyl-1-methanol, excellent turnovers (34000 TONs) were observed 4-methoxybenzyl alcohol. To demonstrate synthetic these systems, high-yield reactions (up to 98%)...
An overview of the state-of-the-art advancements is provided on use transition-metal based molecular catalysts to produce hydrogen from liquid organic carriers (LOHCs) derived renewable sources such as alcohols.
We report here the synthesis and characterization of a series NNN pincer-nickel complexes type (R2NNN)NiCl2(CH3CN) (R = iPr, tBu, Cy, Ph, p-F-C6H4) based on bis(imino)pyridine ligands. In solution, these are found to be equilibrium mixtures containing one two pincer ligands, respectively. While crystal structure former was reported by us recently for R we latter in this study p-F-C6H4. The considered pincer-Ni have been successfully employed accomplish catalytic β-alkylation several...
Herein, we report the exceptional activity of pincer-ruthenium catalysts in value-addition ethanol via its high yield conversion ( ca. 73%) to green hydrogen and precious acetic acid with selectivity 100%) under ambient conditions.
Abstract Readily available and inexpensive bromide salt based on earth‐abundant nickel has been used to catalyze the Suzuki coupling of a variety aryl halides (ca. 37 examples) in high yields under ambient conditions with good functional group tolerance. The reactivity various follows corresponding C−X (X=I, Br Cl) bond strength order Ar−I>Ar−Br>Ar−Cl. EPR analysis, mercury‐drop experiments reactions radical scavenger such as TEMPO point involvement well‐defined molecular species that...
