The mechanism of formation of TTN (an important precursor to tetrathiafulvalene (TTF)) from 4,5-bis(benzoylthio)-1,3-dithiole-2-thione is discussed. Contrary to previous reports, ethylenetetrathiolate is not an intermediate in this synthesis, whereas 4,5-vinylenedithio-1,3-dithiole-2-thione is likely to be. The latter is prepared by a new synthesis and converted into TTN in one step.
讨论了由4,5-双(苯甲酰硫基)-1,3-二硫代-2-硫酮形成TTN(四硫富瓦烯(TTF)的重要前体)的机理。与以前的报告相反,四硫代乙烯盐不是该合成的中间体,而4,5-乙烯基二硫-1,3-二硫基-2-硫酮则可能是中间体。后者是通过新的合成方法制备的,并一步一步转化为TTN。
