| 摘 要： | 用电化学和表面增强拉曼散射(SERS)光谱方法研究了2，6-二甲基4(3-硝基苯基)-3，5(二甲酸二乙酯基)-1，4-二氢吡啶(NIT)的电化学反应机理．发现当电位正于1．0V时，NIT开始氧化，失去2个电子和2个质子，形成吡啶衍生物．当电位负于-0．25V时，该吡啶衍生物被还原．但硝基苯中的硝基并不发生电化学反应．

| Abstract: | The electrochemical behavior and its mechanism of diethyl 2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylates (NIT) were studied using the electrochemical and Raman spectroscopic methods. The results indicate that NIT begins to be oxidized when the potential is more positive than 1.0?V. NIT would lose two electrons and two protons, forming the pyridine derivative. The pyridine derivative would be reduced when the potential is more negative than -0.25?V. The electrochemical reaction of the nitro group of 4-(3-nitrophenyl) in NIT does not occur. |
