COUPLED HETEROARYL COMPOUNDS VIA REARRANGEMENT OF HALOGENATED HETEROAROMATICS FOLLOWED BY OXIDATIVE COUPLING (COUPLED TRICYCLIC CORE COMPOUNDS)

The inventions disclosed and described herein relate to new and efficient generic methods for making a wide variety of compounds having HAr - Z - Har tricyclic cores (II) from intermediates (I), wherein HAr is an optionally substituted five or six membered heteroaryl ring, and Hal is a halogen, and Z is a bridging radical, such as S, Sc, NRS, C(O), C(O)C(O), Si(R5)2, SO, S02, PRS, BRS, C(R5)2 or P(O)R5 and both HAr are covalently bound to one another. 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 (IT) can be useful for making semi-conducting materials, and/or electronic devices comprising those materials. Acyl compounds can be prepared. Heteroary- lene substituents can be used. The core tricyclic core can be coupled to itself. The Z group also can be strong electron-withdrawing groups such as C=C(CN)2 or [C=C(CN)2]2. Organic electronic devices can be made including field-effect transistors. (Formula I, II)
