以二硫化碳和水合肼为原料合成了2,5-二巯基-1,3,4-噻二唑(DMcT),并采用元素分析、Raman光谱和红外(IR)光谱对DMcT的结构进行了表征.DMcT的循环伏安曲线表明,在室温下DMcT的氧化还原反应速度很慢,且酸碱条件对DMcT氧化还原反应有很大的影响.加入三乙胺之后,DMcT的氧化反应更加容易,还原峰电流增大,但对还原峰电位的影响不大;相反,当甲磺酸存在时,DMcT的氧化反应更难进行,而还原反应变得更加容易.
2,5-dimereapto-1,3,4-thiadiazole(DMcT) is synthesized by hydrazine hydrate and carbon disulfide. The structure of DMcT is determined by elemental analysis, Raman spectra and infrared spectra. Cyclic vohammetry curves of DMcT show that the redox reaction of DMcT is rather slow at room temperature, and the influence of acidic and basic condition on the redox behavior of DMcT is great. The addition of triethylamine facilitates the oxidation of DMcT and makes the peak current increase, but does not influence the reduction peak potential of DMcT. On the contrary, the addition of CF_3COOH makes the oxidation of DMcT harder than the neutral condition, but facilitates the reduction of DMcT.
