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.
我们开发了一种二苯并四硫富瓦烯 (DBTTF) 衍生物的两步合成方法,方法是将铟催化的草酸和富电子芳族二硫醇的还原二硫代缩醛化反应与所得二硫代缩醛的后续氧化相结合。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了相应的苯并-1,3-二硫代富烯衍生物。
