Synthesis and electrochemical properties of acetylferrocene semicarbazone

以二茂铁为原料通过两步反应合成了标题化合物,其结构通过IR、1HNMR和元素分析予以确证。采用循环伏安法测定了该化合物在无水乙腈溶液中的电化学性能。实验结果表明,在扫描范围(-0.1～0.83 V)内,标题化合物出现了一对氧化还原峰;当扫描速度在100～500 mV/s范围时,其半波电位(E1/2)为0.476～0.466 V;峰电流比(Ipa/Ipc)为1.387～1.269,并且峰电流(Ip)与扫描速度平方根(ν1/2)呈良好的线性关系。

Acetylferrocene semiearbazone （AFS） was synthe- sized from ferrocene. The structure of the semicarbazone was confirmed by IR, I HNMB. and elementary analysis. The elec- trochemical properties of AFS in anhydrous acetonitrile solu- tion were investigated by CV（ cyclic voltammetry）. The result showed that a pair of redox wave appeared in the rang of - 0. I -0. 83 V. When scan rate is between 100 mV/s to 500 mV/s, the half-wave potential（ E1/2 ） is 0. 476 - 0.466V, and the ratio of 1pa and I is 1. 387 - 1. 269 and the peak current （Ip） has fine liner relationship with the square root of scan rate（ v^1/2 ）.
