Description

2,2'-bithiophene is an intermediate widely used for the synthesis of small molecules or polymer semiconductors in application of organic electronics.?It has proven that?2,2'-bithiophene exists as a mixture of the cis-like and the trans-like planar structures. 5,5'-positions of?2,2'-bithiophene are easily accessible for bromination and stannylation to give 5,5'-dibromo-2,2'-bithiophene or 5,5'-trimethylstannyl-2,2'-bithiophene, which can be used for direct arylation reactions.
