afforded dialdehydes substituted at the 6-position and the furan ring, while the thienyl derivatives and the phenyl derivatives mainly gave monoformylated derivatives substituted at the 6-position. The obtained mono- and dialdehydes were converted into monoaryl-substituted 2,2′-ethanediylidene-bis(1,3-dithiole) derivatives and heteroaromatic ring-inserted [3]dendralene derivatives with triple 1,3-dithiol-2-ylidenes
摘要 检查了各种6-芳基-1,4-二硫富富烯上的Vilsmeier-Haack型甲酰化。在室温下用过量的POCl 3在DMF中处理的呋喃基衍生物主要提供在6-位取代的二醛和呋喃环,而噻吩基衍生物和苯基衍生物主要提供在6-位取代的单甲酰化衍生物。将获得的单醛和二醛转化为单芳基取代的2,2'-乙二亚甲基-双(1,3-二硫醇)衍生物和杂芳环插入的[3]树枝状烯醛衍生物与三重1,3-二硫醇-2-亚烷基和他们的TTF融合类似物。还通过循环伏安法研究了新的π电子供体的电化学性质。 检查了各种6-芳基-1,4-二硫富富烯上的Vilsmeier-Haack型甲酰化。在室温下用过量的POCl 3在DMF中处理的呋喃基衍生物主要提供在6-位取代的二醛和呋喃环,而噻吩基衍生物和苯基衍生物主要提供在6-位取代的单甲酰化衍生物。将获得的单醛和二醛转化为单芳基取代的2,2'-乙二亚甲基-双(1,3-二硫醇)衍生物和杂
