摘要
在DMF-MeOH体系中,2-氰乙硫基-3,6,7-三取代四硫富瓦烯与等物质的量的氢氧化铯作用,生成去保护的3,6,7-三取代四硫富瓦烯-2-硫负离子,后者与三(碘乙基)胺或1,3,5-三(溴甲基)苯反应生成带有3个四硫富瓦烯取代的三脚型电子给体化合物。用NMR、MS和元素分析等手段证实了产物的结构,并用CVs研究了它们的电化学性质。对循环伏安图进行电流微分结果证明,标题化合物的电极反应为分步过程。
2-Cyanoethylthio-3, 6, 7-trisubstituted tetrathiaful- valenes entered into reaction with equimolar cesium hydroxide to give 3,6,7-trisubstituted tetrathiafulvalenyl-2-thio anions in the DMF-MeOH solution.The anions could continue to react with tri （ 2- iodoethyl） amine or 1,3,5- tri （bromomethyl） benzene to yield the tripod-type compounds with three TrF units as the electronic donor. Their structure was confirmed by ^1HNMR, MS spectrometry and elemental analysis and their electrochemical behavior was investigated by means of the cyclic voltammetry.The results of differentiation on electric current of CVs showed clearly that the electrode reaction of target compounds was a stepwise process.
