以四(氰乙硫基)四硫富瓦烯为原料经醇钠消去氰乙基生成四硫富瓦烯四硫盐， 再与二元卤代烷烃化反应，除了得到三种文献报道的双(亚烷二硫基)四硫富瓦烯衍 生物外，还得到三种新的“四桥”双—四硫富瓦烯衍生物，为“桥式”双—四硫富 瓦烯衍生物的合成提出了一种新的方法．并研究了它们的循环伏安图、电化学性质 和紫外—可见光光谱．

2,3,6,7-Tetrakis(2'-cyanoethylthio)-tetrathiafulvalene was treated with sodium alkoxide to give tetrathiafulvalene-2,3,6,7-tetranthiolate. The generated thiolate was trapped by subsequent quenching with dibromoalkylane, yielding the corresponding bis(alkylenedithio) compounds and four-bridged bistetrathiafulvalenes. Their electrochemical properties of bis(alkylenedithio) tetrathiafulvalene and four-bridged bis-tetrathiafulvalenes were studied by cyclic voltammetry. UV/vis spectra of these compounds are also discussed.

Key words: tetrathiafulvalene;sodium alkoxide;ELECTROCHEMISTRY;DERIVATIVES, ULTRAVIOLET SPECTROSCOPY
