Synthesis of donor-acceptor substituted oligothiophenes by Stille coupling |
|
| Abstract: | A synthesis of donor-acceptor-substituted oligothiophenes by Stille coupling is described. The 5′-estanyl derivatives, readily prepared from 5-alkoxy- and 5-amino-2,2′-bithiophenes 7 were coupled with the appropriate aryl or heteroaryl bromides to give the title compounds. |
