Abnormal polarization change in anodic dissolution of aluminium at high current densities
(Elsevier, 1981)
Two types of anodic oxidation of aluminum have been recognized in the past: a) oxidation requiring a steady increase of voltage drop across the interface up to a few hundred volts in order to overcome the resistance of ...
Deuterium‐induced 13C nuclear magnetic resonance isotope shifts and 13C-2H couplings for signal assignments and determination of deuteration site in cyclooctanone
(Wiley, 1981)
Unambiguous signal assignments in the 13C spectra of monodeuterated cyclooctanones derived from the lead tetraacetate or silver oxide/bromine oxidations of the corresponding 1‐monodeutero‐alcohols have been obtained from ...
The conformational equilibrium of 1,3-dichloro-5-methylcyclohexane
(Elsevier, 1981)
Two of the stereoisomers of the title compound were prepared and their dipole moments were measured. For the r-1,c-3-dichloro-t-5-methylcyclohexane, the free energy difference between conformers with axial-axial (aa) and ...
Mass spectrometric analysis of the carbon content in the plasma of a horizontal electric arc burning in a graphite tube / Massenspektrometrische Analyse des Kohlenstoffgehaltes im Plasma einer horizontalen Bogenentladung in einem Graphitrohr
(Springer Science and Business Media LLC, 1981)
The carbon content in the plasma of a horizontal electric arc in a graphite tube, burning in air, in the presence of an inhomogeneous magnetic field has been determined. The modifications with one and two rotating arc ...
Ferrous ion induced decomposition of alkyl hypochlorites
(Elsevier, 1981)
The decomposition of primary, secondary and tertiary alkyl hypochlorites induced by ferrous and other one-electron oxidizable metal ions leads to δ-chloro alcohols in yields of 34-76%. In decomposition of tertiary alkyl ...
Some Observations Concerning 1H‐NMR. Spectra of 5‐hydroxy‐ and 5‐acetoxy‐steroid compounds
(Wiley-Blackwell, 1981)
It was found that analysis of the 1H‐NMR. signals (at 360 (preferably) and/or 100 MHz) of the protons at C (4) and of the equatorial α‐proton at C (6), particularly when these are located in the 2–3 ppm region and therefore ...
