我们已经开发了一种两步合成二苯并四硫富瓦烯（DBTTF）衍生物相结合的铟催化还原草酸和富电子芳香族二硫醇的二硫代缩醛与随后的氧化所得的二硫代缩醛。富电子芳族二硫醇与9-芴羧酸衍生物或二羧酸的相同转化有效地产生相应的苯并-1，3-二硫富烯衍生物。
We have developed a two-step synthesis of dibenzotetrathiafulvalene (DBTTF) derivatives by combining the indium-catalyzed reductive dithioacetalization of oxalic acid and electron-rich aromatic dithiols with a subsequent oxidation of the resultant dithioacetals. The same transformation of electron-rich aromatic dithiols with either 9-fluorenecarboxylic acid derivatives or dicarboxylic acids effectively produced the corresponding benzo-1,3-dithiafulvene derivatives.
