The redox characteristics of the title compounds are extensively studied using DC-, cyclic voltammetry, coulometry, and controlled potential electrolysis in benzonitrile at platinum electrodes. These compounds are oxidized in one-electron transfer process followed by deprotonation which leads to dimerization. The reduction process differs according to the nature of the compound and the electron-withdrawing power of the substituent in the α-position. They can be reduced in a single two electron or two one electron waves leading in both cases to saturation of the hydrazonic moiety.
在苯腈中,通过直流、循环伏安法、库仑法和可控电位电解法对标题化合物的氧化还原特性进行了广泛研究。这些化合物在单电子转移过程中被氧化,随后发生脱质子化反应,导致二聚化。还原过程因化合物的性质和α位取代基的吸电子能力而异。它们可以通过单个双电子或两个单电子波进行还原,两种情况都会导致肼基部分饱和。
