Copper-mediated pentafluoroethylation of arenediazonium tetrafluoroborates with tetrafluoroethylene (TFE) on-site generated from TMSCF3 has been developed as a new method to prepare pentafluoroethyl arenes. The active pentafluoroethylation reagent ?CuC2F5? is pre-generated from CuSCN, TFE and CsF, and its generation and further reaction are strongly solvent-dependent. This pentafluoroethylation reaction represents the first example of Sandmeyer-type pentafluoroethylation, which exhibits good functional group tolerance and potential applications for the synthesis of complicated bioactive compounds.

Cuprous oxide (Cu2O) nanowire films were in situ grown from pre-deposited cuprous thiocyanate (CuSCN) films which acted as sacrificial precursors. The synthesis was processed in air from NaOH solution, providing an appealing alternative to nanowire-based porous films. Plausible solid-liquid interface reactions were described. Structural analysis showed that Cu 2O nanowires were p-type polycrystalline semiconductor, with high aspect ratio of 10-30 nm in diameter and more than 1 um in length, and they were found to be interlaced with each other in the formation of interpenetrating networks within the Cu2O film which possessed large-area uniformity. It is noteworthy that the nanowire-based films actually are porous films embedded with various interwire spaces and cavities. Photoelectrochemical measurements revealed that a Cu2O film with thickness of 500-1000 nm generated zero-bias photocurrent of approximately 1.5 muA cm-2. The present synthesis is facile and low-cost, and is expected to be suitable for mass production of large-area semiconductor films under ambient condition.

We have created a facial self-templated method to synthesize three distinct nanostructures, including the unique edge-cut Cu@Ni nanocubes, edge-notched Cu@Ni nanocubes, and mesoporous Cu-Ni nanocages by selective wet chemical etching method. Moreover, in the synthesis process, the corners of edge-cut Cu@Ni nanocubes and mesoporous Cu-Ni nanocages can be etched to produce the highly catalytically active (111) facets. Impressively, compared to edge-notched Cu@Ni nanocubes and edge-cut Cu@Ni nanocubes, the Cu-Ni nanocages exhibit higher electrocatalytic activity in the hydrogen evolution reaction (HER) under alkaline conditions. When obtained overpotential is 140 mV, the current density can reach 10 mA cm-2 meanwhile, the corresponding Tafel slope is 79 mV dec-1. Moreover, from the calculation results of density functional theory (DFT), it can be found that the reason why the activity of pure Ni is lower than that of Cu-Ni alloy is that the adsorption energy of the intermediate state (adsorbed H?) is too strong. Meanwhile the Gibbs free-energy (|DeltaGH?|) of (111) facets is smaller than that of (100) facets, which brings more active sites or adsorbs more hydrogen.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 13395-16-9 is helpful to your research. Related Products of 13395-16-9
