摘要

评估了邻甲苯胺在缓冲液/乙腈混合物(70/30)和不同 pH 值下的电化学氧化作用。电化学结果证实,邻甲苯胺在酸性、中性和碱性溶液中的电氧化机理是不同的,并得到了氧化机理不同的三个 pH 区:在第一区,是 E 机理下的可逆氧化反应;在第二区,观察到了 ECDispE 机理下的两个单电子氧化还原反应;在第三区,观察到了 ECE 机理的证据。接着,在第三区域报告了一种新偶氮化合物的电合成。该过程涉及邻甲苯胺在磷酸缓冲水溶液(pH = 7.2)中的电化学氧化,在一个使用碳阳极的分层电池中进行。

Two interesting reports in electrochemical oxidation of o-tolidine: presentation ECDispE mechanism and electrosynthesis of a diazine compound

Electrochemical oxidation of o-tolidine has been assessed in a mixture (70/30) of buffer/acetonitrile and various pHs. The electrochemical results corroborate that the mechanism of electrooxidation of o-tolidine acidic, neutral, and alkaline solutions are different, and three pH zones with different oxidation mechanisms were obtained: in the first region, a reversible oxidation reaction under the E mechanism, in the second region, observing the two one-electron oxidation–reduction under the ECDispE mechanism, and observation of the evidence of the ECE mechanism in the third region. In the continuation, electrosynthesis of a new azo compound has been reported in the third region. This process involves the electrochemical oxidation of o-tolidine in an aqueous phosphate buffer (pH = 7.2) in a divided cell using a carbon anode.
