  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, 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, Se, NR5, C(O), C(O)C(O), Si(R5)2, SO, SO2, PR5, BR5, 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 (II) can be useful for making semi-conducting materials, and/or electronic devices comprising those materials. Acyl compounds can be prepared. Heteroarylene substituents can be used. The 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.

• Deprotonative C–H Silylation of Functionalized Arenes and Heteroarenes Using Trifluoromethyltrialkylsilane with Fluoride
  作者：Midori Sasaki、Yoshinori Kondo

  DOI：10.1021/ol503671b

  日期：2015.2.20

  A highly selective C–H silylation reaction of functionalized arenes and heteroarenes was developed using Ruppert–Prakash reagent (TMSCF3) activated by alkali metal fluoride. TMSCF3 is considered to play dual roles as a precursor of a mild base and also as a silicon electrophile. The silylation is compatible with sensitive functional groups such as halogen and nitro groups.

  使用被碱金属氟化物活化的Ruppert-Prakash试剂（TMSCF 3），开发了功能化芳烃和杂芳烃的高选择性C-H甲硅烷基化反应。TMSCF 3被认为是温和碱的前体以及亲电子体具有双重作用。甲硅烷基化与敏感的官能团如卤素和硝基相容。
