Electrochemical Behaviour of Cyanoethenyl Aniline Derivatives

本文利用循环伏安法研究了电子给-受体模型化合物——氰基乙烯基苯胺衍生物的电化学行为,并对推电子取代基团—NH_2和—N(CH_3)_2与吸电子取代基团氰基乙烯基对化合物电化学行为的影响进行了较为详细的讨论.提出了这些化合物的电氧化态和电还原态的结构,通过分析比较叔、仲和伯自由基对化合物电化学行为的影响,探讨了电极反应机理.

The electrochemical behaviour of the electron donor-acceptor model compounds,cya-noethenyl aniline derivatives was investigated by cyclic voltammetry.The effects of donating electron group-NH2,-N(CH3)2 and withdrawing electron group cyanothenyl group on electrochemical behaviour of these compounds were studied in detail.The structures of electroox-idation and electroreduction state of these compounds were proposed,and the mechanism of the electrode reaction was studied by comparing the effects of tert-radical,sec-radical and pri-radical on electrochemical behaviour of these compounds.
