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...

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...
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...
e, Reaction of NADH with H2O2 under copper(ii)-catalysed or copper-free conditions. Experimental mass spectrometry peaks and calculated masses of molecular ions are indicated. ES+, electrospray ionization mass spectrometry. f, Kinetics of NADH oxidation in the presence of H2O2 and copper(ii). ...
Hindustan Copper Limited, (HCL) a government of India undertaking was incorporated in the year 1967. In the Indian copper business, HCL has come a long way down the beaten track carving a niche for itself by spearheading the country's industrial growth with the spirit of an undaunted pioneer...
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 ...
This reaction is basically can be used to distinguish between primary, secondary and tertiary alcohols on different given temperatures. Primary alcohol on reaction with copper powder yield corresponding aldehyde, secondary carbon will yield ketone, and tertiary carbon will yield the corresponding alkene....
