Derivatives involving two tetrathiafulvalene moieties linked by an alkylenedithio bridge and long-chain substituents were synthesized by the condensation of alkylenedithiobis(1,3-dithiole-2-triphenylphosphonium) perchlorates and 2-ethylseleno-4-heptadecyl-1,3-dithiolium tetrafluoroborate in the presence of triethylamine. The derivative involving a hexadecyclethylenedithio substituent was synthesized by the coupling of the corresponding 1,3-dithiol-2-one and 1,3-dithiole-2-thione derivatives in the presence of triethyl phosphite.
通过缩合二硫代二丙烯双(1,3-二硫杂环戊烯-2-三苯基鏻)高氯酸盐和2-乙基硒-4-十七烷基-1,3-二硫杂环戊烯四氟硼酸盐,并在三乙胺存在下,合成了由两个四硫富瓦烯部分通过二硫代二丙烯桥连接的长链取代基衍生物。通过在亚磷酸三乙酯存在下,将相应的1,3-二硫杂环戊烯-2-酮和1,3-二硫杂环戊烯-2-硫酮衍生物偶联,合成了由十六烷基二硫代二丙烯取代基的衍生物。
