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
2,3 - bis (2 - cyanoethylthio) -6,7 - (1,3 - propylene - dithio) tetrathiafulvalene (5) in the role of sodium methoxide Ethyl group. After the first elimination, the sodium thiolate (6) in the compound reacts with p-chlorobenzene to form a new “bridge” -distetrathiafulvalene derivative (7), which in turn is reacted with sodium methoxide And the reaction of chlorinated xylene to form a new “bridge” bis-tetrathiafulvalene derivative (8), a novel method for the synthesis of tetrathiafulvalene derivatives was proposed. The results show that the cyclic voltammograms of two kinds of “bridge” -distetrathiafulvalene derivatives have two double electron oxidation-reduction potentials, and the UV absorption is significantly enhanced
