The stable, crystalline 1,3-dibromo-4,6-dicyanothieno<3,4-c>thiophene (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.
