Unexpected “Two‐Electron” Transfer in Cyclic Hydrazines–a Voltammetric Analysis

Conformational changes could be shown to give rise to unusual cyclovoltammograms in the case of 1a and 1b. At low temperatures, compounds 1a and 1b formally show a two-electron transfer; in the case of 1a the rare crossing effect is observed. All other methods of conformation analysis failed in this case.
