3,4-Dibromothiophene-2,5-dicarboxaldehyde (25373-20-0) 's Synthetic route

Improved synthesis of dithieno[3,2-b:2′,3′-d]thiophene (DTT) and derivatives for cross coupling

Frey, Joseph  Bond, Andrew D.  Holmes, Andrew B.

An improved synthesis of dithieno[3,2-b:2′,3′-d]thiophene (DTT) and its 2,6- and 3,5-dibromo derivatives has been devised; Stille cross coupling of 2,5-(bistrimethylstannyl)-DTT afforded the oligomer 12.
