The synthesis of some functionalised, isomeric, symmetrical tetrathiafulvalene derivatives containing 4,5-(ethylenedithio)-1,3-dithiole and 4,5-(propylenedithio)-1,3-dithiole units is described. These contain hydroxy, chloro and cyano functionalities (4, 6, 9 and 12). Interestingly, attempted coupling of 4,5-bis(propargylthio)-1,3-dithiole-2-thione 13, to obtain the corresponding TTF, 14 afforded the
描述了一些含有4,5-(亚乙二硫基)-1,3-二硫醇和4,5-(亚丙二硫基)-1,3-二硫醇单元的官能化的,异构的,对称的四硫富瓦烯衍生物的合成。这些含有羟基,氯和氰基官能团(4,6,9和12)。有趣的是,尝试将4,5-双(炔丙基硫基)-1,3-二硫基-2-硫酮13偶联以获得相应的TTF 14,得到了新颖的硫酮5-甲基硫代[2,3-d] -1, 3-二硫代-2-硫酮15。亚磷酸三甲酯存在下硫酮15的自偶联提供了新的功能化二噻吩四硫富富瓦烯16。的4,5-双(propargyldithio)-1,3-二硫杂环-2-硫酮的X射线crysal结构13和5-甲基噻吩并[2,3-d] -1,3-二硫杂环-2-硫酮15中描述。
