Abstract

Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as model compds. A reaction mechanism involving methoxyl radicals formed by discharge of methanol on BDD has been proposed in order to explain the behavior of BDD for the C-C cleavage of 1,2-diphenyl-ethane derivs. [on SciFinder (R)]

Boron

Boron is a chemical element with the symbol B and atomic number 5. In its crystalline form it is a brittle, dark, lustrous metalloid; in its amorphous form it is a brown powder. As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride. Boron is synthesized entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Earth's crust.

Rotating disk electrode

In analytical chemistry, a rotating disk electrode (RDE) is a working electrode used in three-electrode systems for hydrodynamic voltammetry. The electrode rotates during experiments, inducing a flux of analyte to the electrode. These working electrodes are used in electrochemical studies when investigating reaction mechanisms related to redox chemistry, among other chemical phenomena. The more complex rotating ring-disk electrode can be used as a rotating disk electrode if the ring is left inactive during the experiment.

Rotating ring-disk electrode

In analytical chemistry, a rotating ring-disk electrode (RRDE) is a double working electrode used in hydrodynamic voltammetry, very similar to a rotating disk electrode (RDE). The electrode rotates during experiments inducing a flux of analyte to the electrode. This system used in electrochemical studies when investigating reaction mechanisms related to redox chemistry and other chemical phenomena. The difference between a rotating ring-disk electrode and a rotating disk electrode is the addition of a second working electrode in the form of a ring around the central disk of the first working electrode.
