新型刚性芳环桥连甲硫基-二茂铁苯胺化合物的合成及其电化学性质研究

Synthesis and Electrochemical Performance of Novel Thiomethyl-containing Ferrocenylarylamines Linked by Rigid Aromatic Spacer

二茂铁苯胺(3a～3c)分别与对甲硫基苯甲醛反应合成了三个新型的含对甲硫苯基的二茂铁席夫碱化合物(4a～4c);4a和4b经硼氢化钠还原碳氮双键得到两个N-(对甲硫苄基)二茂铁苯胺化合物——N-(对甲硫苄基)对二茂铁苯胺(5a)和N-(对甲硫苄基)间二茂铁苯胺(5b),其结构经1H NMR,IR和MS表征。电化学循环伏安研究表明,4a～4c与5a,5b略有差异,其中5a不易得到电子。

Three novel Schiff base,thiomethylphentl-containing ferrocene derivatives（4a～4c）,were designed and synthesized by the reaction of ferrocenyphenylamines（3a～3c） with p-methylthiobenzaldehyde,respectively.Two thiomethyl-containing ferrocenylarylamines（5a,5b） were obtained by reduction of 4a（or 4b） with sodium borohydride.The structures were characterized by 1H NMR,IR and HR-MS.The electrochemical properties were investigated by voltammogram.The results showed that the electrochemical properties of 4a～4c and 5a,5b were slightly different.The capacity to acquire electron with substitution on p-position of ferrocene was slightly difficult.
