  Synthesis of the First Thieno[3,4-c]thiophene Stabilized Only by Electronic Effects

  摘要：

  The stable, crystalline 1,3-dibromo-4,6-dicyanothieno[3,4-c]thio (3a) has been synthesized. This is the first example of a thieno[3,4-c]thiophene stabilized solely by electronic effects. The dicarbomethoxy dibromo analog 3b and the tetrabromo analog 3c were also-generated and found to be considerably less stable.
