  A catalyst system comprising Fe2(OtBu)6 and an N-heterocyclic carbene ligand enables efficient syntheses of (hetero)biaryls from the reactions of aryl Grignard reagents with a diverse spectrum of (hetero)aryl chlorides. Amongst the alkoxide and amide counterions investigated, tert-butoxide was the most effective in inhibiting the homocoupling of arylmagnesiums.

  包含Fe2(OtBu)6和一个N-杂环卡宾配体的催化体系能够高效合成（杂）双芳基，这是通过芳基格氏试剂与各种（杂）芳基氯化物的反应实现的。在研究过的烷氧化物和酰胺阴离子中，叔丁氧化物在抑制芳基镁的同偶联反应中效果最佳。

• A new approach to pyridines through the reactions of methyl ketones with 1,2,4-triazines
  作者：Shu-Wen Wang、Wei-Si Guo、Li-Rong Wen、Ming Li

  DOI：10.1039/c4ra11294f

  日期：——

  A new route to prepare pyridine derivatives based on inverse electron demand Diels–Alder/retro-Diels–Alder reactions of ketones with 1,2,4-triazines is reported. It is the first time using methyl ketones directly as a dienophile to react with 1,2,4-triazines without enamine intermediates, which is complementary to the classical Boger reaction.

  报道了一种基于逆电子需求的酮与1,2,4-三嗪的Diels-Alder / retro-Diels-Alder反应制备吡啶衍生物的新途径。这是第一次直接将甲基酮作为亲二烯体与1,2,4-三嗪反应，而没有烯胺中间体，这是对经典的Boger反应的补充。
