Electron Transfer Initiated Reactions: Bond Formation and Bond Dissociation

“…The addition of an electron-rich molecule to an oxidized species such as a radical cation is one of the most commonly reported. The oxidative coupling of electron-donating substituted alkenes is a well-known process. ,– The coupling takes place at the level of the radical cation generated by the oxidation of the parent molecule with either another radical cation or even the parent olefin. In the latter case another ET usually takes place, especially under electrochemical conditions.…”

Electrochemical Impedance Spectroscopy on 3‐D Inhomogeneous Surfaces Corrosion Inhibition of Carbon Steel in Weakly Acidic NaCl Solutions

“…Consequently, in aerated weakly acidic solutions, the corrosion process is expected to be determined by both cathodic reactions where the hydrogen evolution may proceed under mixed charge-transfer and mass transport control depending on the pH of the solution. Additionally, in aerated solutions the corrossion process is further complicated by the time-dependent formation of 3-D porous layers of corrosion products leading to localized corrosion phenomena [5][6][7][8][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. In deaerated weakly acidic solutions, 3-D surface layers may also be formed due to the precipitation of Fe(II)-hydrolysis products and iron carbonate compounds in the presence of CO 2 in the electrolyte.…”
