The reaction of HCl with clean, Cu(100) and (111), and Au/ Cu(100) surfaces was investigated using x-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) under ultra high vacuum (UHV) conditions. Exposure of the Cu(100) and (111) samples to HCl at room ...
Fluorination with fluorine produces copper(II) fluoride, CuF2. Adding potassium ferrocyanide to CuCl2 aqueous solution precipitates out reddish brown cupric ferrocyanide. Reaction with caustic soda forms blue cupric hydroxide: CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl Black copper(II) sulfide, CuS, is obt...
In addition to the control experiments described in Table 1, the CuOTf-catalysed chlorination of 1a by dichloramine-T under the various reaction conditions described in Supplementary Table 1 were examined. Along with NaHCO3 (1.5 equiv.) and 4 Å MS in acetonitrile at room temperature for 24...
To write the equation for the reaction between copper (Cu) and concentrated nitric acid (HNO3), we need to follow these steps:Step 1: Identify the reactants The reactants in this reaction are: - Copper (Cu) - Concentrated Nitri
Compounds of the type M( L) nCl 2, where M is Cu(II) or Ni(II), L is 2,2′-bipyridine, 1,10-phenanthroline, ethylenediamine, or 8-aminoquinoline, and n is 1, 2, or 3, were reacted with HCl gas. The reaction was carried out under anhydrous conditions at room temperature and ...
complex ion [Cu(CH3CN)4]+ which can be precipitated with large anions such as ClO4 - or PF6- . Reactions with alkoxides of alkali metals produce yellow copper(I) alkoxides. For example, reaction with sodium ethoxide yield copper(I) ethoxide, a yellow compound that can be sublimed from...
Reaction with caustic soda forms blue cupric hydroxide: CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl Black copper(II) sulfide, CuS, is obtained when hydrogen sulfide is passed through dissolved CuCl2. CuCl2 forms several copper(II) complexes with several types of ligands in aqueous solutions. ...
This paper presents a new ground state (1 (2)A(')) electronic potential energy surface for the F((2)P)+HCl-->HF+Cl((2)P) reaction. The ab initio calculatio... Deskevich,P Michael,Hayes,... - 《Journal of Chemical Physics》 被引量: 74发表: 2006年 Ionic Liquids Made with Dime...
(entry 11). The yield was increased to 50% by using 10 mol % copper(I) salt and 12 mol % NHC-L4 (entry 12). By increasing the amount of LiOtBu from 1 equiv to 2 equiv, the yield was further increased to 85% with 89% ee (entry 13). Performing the reaction at −20...
With the addition of 1-50 mM HCl, the size of the copper branches was dramatically reduced; in particular, the average size of the elementary branches in the foam wall was reduced from 300 to 50 nm, forming nanostructured porous electrodes ideally suited for electrochemical and catalytic ...
