  摘要：

  The cycloaddition of hex-3-yn-2,5-dione onto a pi-CS2 Iron complex 3 and on 3-thioxo-1,2-dithioles affords diacetylated intermediates which can be readily converted into di or tetraacetylated derivatives of the 1,3-dithiole (5,6) and tetrathiafulvalene (2,8) series, some representative electrochemical and structural features of which being also presented.

  The synthesis of highly extended and sulfur rich tetrathiafulvalene derivatives, designed to avoid any internal cyclisation during their subsequent electrooxidation, is described. Their π-donating ability is confirmed by cyclic voltammetry, as well as the good stability of each of their oxidized species (up to an hexacationic state in one case).

  描述了高度扩展的和富硫的四硫富瓦烯衍生物的合成，旨在避免在其随后的电氧化过程中发生任何内部环化。通过循环伏安法证实了它们的π供电能力，以及它们每个氧化物种的良好稳定性（在一种情况下高达六阳离子状态）。
