Monovalent copper as a potential catalyst for formation of acetaldehyde via the migration of methyl radicals to the coordinated carbonyl in the complex (CO... A Szulc,M Dan,H Cohen - 《Inorganica Chimica Acta》 被引量: 7发表: 1998年 Cyanide as a copper-directed inhibitor of amine oxidases...
An efficient methodology has been developed for the synthesis of nitriles through an aerobic oxidative reaction of alcohols and ammonium formate with copper as a homogeneous catalyst under a normal air atmosphere and solvent-free conditions. This protocol uses the air as a green oxidant and ammonium...
As harmaline should exist in the soil in which a harmaline-producing plant, such as P. harmala, grows, we hypothesized that harmaline is degraded and metabolized by microorganisms in the soil. Here, we describe the discovery of copper amine oxidase (CAO) as a harmaline-metabolic enzyme, from...
One Pot Synthesis of Ultra-High Copper Contented Cu/SBA-15 Material as Excellent Catalyst in the Hydrogenation of Dimethyl Oxalate to Ethylene Glycol High copper contented mesoporous Cu/SBA-15 catalysts with high copper dispersion were successfully synthesized via the simple ammonia-driving deposition-pr...
A general method for the coupling of aryl and vinyl halides with diaryl and dialkyl phosphines, as well as with dibutyl phosphite, is reported. This highly efficient transformation is realized through the use of copper(I) iodide as a catalyst, N,N'-dimethylethylenediamine as a ligand, and Cs...
Electrolytic copper is a well-known form of pure, oxygen free copper that is used for industrial applications. In this work, the catalytic potential of this relatively cheap material was studied. The addition of less than 0.015 mol equivalent of copper powder effectively catalysed the one-pot...

ATRP occurred even at a catalyst/initiator molar ratio as low as 0.001 with copper concentration in the produced polymers as low as 6-8 ppm (catalyst/monomer molar ratio = 10(-5)). The catalyst structures were studied by X-ray diffraction and NMR spectroscopy. The activator CuIBr/TPEN ...
These C–H functionalization reactions using a Cu(I) catalyst with loading as low as 0.5 mol.% is applied to the diversification of a wide range of aliphatic acids including drug molecules and natural products. The exceptional compatibility of this catalytic system with a wide range of ...
According to the previous work, ceria (CeO2) is often recognized as a suitable supports to anchor copper because of the strong interaction between copper and ceria. Using the interaction, the copper‒ceria catalyst has shown its unique value in a variety of catalytic reactions, such as low-...
