The electrochemical oxidation of 4-chloroaniline as a model compound in a water/acetonitrile mixture was investigated by cyclic voltammetry and differential pulse voltammetry. It was established that one-electron oxidation of 4-chloroaniline followed by disproportionation reaction affords unstable (4-iminocyclohexa-2,5-dien-1-ylidene)chloronium. In water/acetonitrile mixtures and in the absence of
通过循环伏安法和差分脉冲伏安法研究了 4-氯苯胺作为模型化合物在水/乙腈混合物中的电化学氧化。已确定 4-氯苯胺的单电子氧化随后发生歧化反应得到不稳定的 (4-iminocyclohexa-2,5-dien-1-ylidene) 氯鎓。在水/乙腈混合物中并且在没有亲核试剂的情况下,对生成的氯鎓最可能的反应是水解和p-醌亚胺形成。还在水/乙腈混合物中,在玻璃碳电极上研究了芳基亚磺酸存在下 4-氯苯胺的电化学氧化。已确定在这些条件下,阳极生成的氯鎓与苯亚磺酸反应生成相应的二芳基砜和N-苯基苯磺酰胺衍生物。此外,Gaussian 09W 通过计算中间体和产物的自然电荷、LUMO 轨道能量和热力学稳定性来预测可能的产物。
