“桥式”双四硫富瓦烯衍生物的合成及电化学行为
摘要:
2,3-二(2-氰乙硫基)-6,7-(1,3-亚丙基-二硫基)四硫富瓦烯(5)在甲醇钠的作用下分2次消去氰乙基基团。第1次消去后化合物中的硫醇钠(6)与对氯二甲苯反应生成一种新的"一桥"-双四硫富瓦烯衍生物(7),该衍生物再依次与甲醇钠和对氯二甲苯反应生成一种新的"二桥"-双四硫富瓦烯衍生物(8),为四硫富瓦烯衍生物的合成提出了一种新的方法。研究结果表明,2种"桥式"-双四硫富瓦烯衍生物的循环伏安图有2个双电子氧化-还原电位,其紫外吸收明显增强。

Synthesis and Electrochemical Behaviour of Bridged Bis-tetrathiafulvalenes
Abstract:
A novel method for synthesis of briged bis-tetrathiafulvalenes has ben proposed. 2,3-Bis(2-cyanoethylthio)-6,7-(1,3-propylidenedithio)tetrathiafulvalene(5) was reacted with sodium methoxide to give monothiolate of tetrathiafulvalene(6), which on reacting with p-chloroxylene afforded a monobridged bis-tetrathiafulvalene(7). Deprotection and alkylation of (7) yielded two-bridged bis-tetrathiafulvalene(8). In cyclic voltammograms of both compound(7) and (8) there were two oxidation-reduction peaks. Their UV-Vis spectral absorbances were also found intensified.
