Two heterocyclic compounds based on the thieno[3,4-c]thiophene structure with four aryl substituents were prepared and their behavior in electrooxidation studied. These tetraarylthieno[3,4-c]thiophenes were synthesized in three steps starting from 1,3-dibenzoylmethane in the case of 1,3,4,6-tetraphenyl-2 u 4 i 2 -thieno[3,4-c]thiophene 1a and from 1,3-bis(4'-methoxyphenyl)propane-1,3-dione in the case
制备了两种基于具有四个芳基取代基的噻吩并 [3,4-c] 噻吩结构的杂环化合物,并研究了它们在电氧化中的行为。在 1,3,4,6-四苯基-2 u 4 i 2 -噻吩并 [3,4-c] 的情况下,这些四芳基噻吩并 [3,4-c] 噻吩是从 1,3-二苯甲酰甲烷开始的三个步骤合成的噻吩 1a 和 1,3-双(4'-甲氧基苯基)丙烷-1,3-二酮在 1,3,4,6-四(4'-甲氧基苯基)-2 u 4 i 2-噻吩[ 3,4-c]噻吩1b,一种新化合物。循环和流体动力学伏安分析均表明化合物 1b 有两个可逆的单电子氧化阶段,而对于化合物 1a,只有第一阶段是可逆的。两种化合物的制备性电氧化导致一个噻吩环打开,产生 n-酮-硫酮。
