ClickBETThe mechanism of a bioortogonal click reaction between 2-azidoethanol and coumBARAC has been examined using DFT methods at B3LYP/6-31G(d,p) and M06-2X/6-31G(d,p) computational levels. The regiochemistdoi:10.1007/s11224-017-0991-2Setayesh Ghandiyar...
Continued development of the Sonogashira coupling has made it a well established and versatile reaction for the straightforward formation of C–C bonds, forging the carbon skeletons of broadly useful functionalized molecules. However, asymmetric Sonogash
Triazole functional films have been constructed on copper or the oxidized species of Cu2O and CuO via an in- situ "click-assembly" method [27]. In the above studies, the growth of molecular chains based on the click reaction only occurred in one dimension, and the increase in film ...
control experiments with different photocatalyst, and DFT calculation studies have proven that the current reaction proceeds via visible light-induced redox-neutral reductive quenching radical mechanism, which is a completely different approach as compared to the traditional transition metal-catalyzed two-elec...
The regioselectivity of the dinuclear-Cu(I)-catalyzed version of the Huisgen reaction, abbreviated in this paper to Cu2AAC, was analyzed using quantum topo
Enhancement in corrosion resistance is due to the formation of the covalent triazole films via the click chemistry reaction catalysed by cuprous oxide. The mechanism of protection is discussed via the surface analysis and the molecular dynamics simulation. Graphical abstract Download: Download high-res ...

The catalytic mechanism for the copper-catalyzed alkyne/azide cycloaddition to form 1,2,3-triazoles. Full size image General procedure for Click reaction with organic halides or aryl azides NaN3 (72 mg, 1.1 mmol), benzyl bromide (119 mg, 1 mmol) or other aryl halides, and terminal alkyne ...
To date, various nanoparticles have been prepared and tested for click chemistry synthesis9,10,11,12,13. Copper nano-catalysts overcome several drawbacks of homogenous catalysis using Cu(I) soluble compounds. Notably, single-molecule spectroscopy supports a heterogeneous-catalysed mechanism of reaction14...
may be used. The optimal harvesting mechanism for a particular embodiment of the present invention will depend largely on a number of interrelated factors, primarily current density, copper concentration in the electrolyte, electrolyte flow rate, and electrolyte temperature. Other contributing factors incl...
