The inventions disclosed and described herein relate to new and efficient generic methods for making a wide variety of compounds having Formulas (I) and (II) as shown below (Formulas (I) and (II)) wherein HAr is an optionally substituted five or six membered heteroaryl ring, and Hal is a halogen, and Y is a bridging radical, such as S, Se, NR5 C(O), C(O)C(O),Si(R5)2, SO, SO2, PR5, BR5, C(R5)2 or P(O)R5. The synthetic methods employ a "Base-Catalyzed Halogen Dance" reaction to prepare a metallated compound comprising a five or six membered heteroaryl ring comprising a halogen atom, and then oxidatively coupling the reactive intermediate compound. The compounds of Formula (II) and/or oligomer or polymers comprising repeat units having Formula (II) can be useful for making semi-conducting materials, and/or electronic devices comprising those materials.
