| 摘 要： | 1,2-Di（p-tolylimino）ethane （Ⅰ） and 1,2-Di（2,4-dimethylphenylimino）ethane （Ⅱ） were synthesized and their electrochemical behavior investigated in dimethylformamide using classical voltammetry, differential pulse voltammetry, cyclic voltammetry, chronoamperometry, controlled potential electrolysis and coulometry. Both bis-Schiff base ligands examined show a cathodic irreversible peak which corresponds to one-electron reduction of the substrate to form anion radical. According to the fact obtained from cyclic voltammetry, that the current function （ip/v^1/2） is a decreasing function of the scan rate, it can be concluded that there is a following coupling chemical reaction （EC mechanism）. Thus, the most probable mechanism of electroreduction of both ligands is the coupling of two radicals to form a dimer.

| Abstract: | 1,2‐Di(p‐tolylimino)ethane ( I ) and 1,2‐Di(2,4‐dimethylphenylimino)ethane ( II ) were synthesized and their electrochemical behavior investigated in dimethylformamide using classical voltammetry, differential pulse voltammetry, cyclic voltammetry, chronoamperometry, controlled potential electrolysis and coulometry. Both bis‐Schiff base ligands examined show a cathodic irreversible peak which corresponds to one‐electron reduction of the substrate to form anion radical. According to the fact obtained from cyclic voltammetry, that the current function (ip/ù1/2) is a decreasing function of the scan rate, it can be concluded that there is a following coupling chemical reaction (EC mechanism). Thus, the most probable mechanism of electroreduction of both ligands is the coupling of two radicals to form a dimer. |
