  金催化剂可以从亚硝基芳烃/烯烃混合物中生成硝酮中间体，从而实现两种不同的催化反应：亚硝基活化的环庚三烯/亚苄基重排

  摘要：

  环庚三烯与亚硝基芳烃的金催化反应可有效地产生硝酮衍生物。该反应序列使我们能够开发金催化的环庚三烯有氧氧化，以使用 CuCl 和亚硝基芳烃作为助催化剂（10-30 mol%）提供苯甲醛衍生物。我们的密度泛函理论计算支持一种新的亚硝基活化重排，tropylium → 亚苄基。使用相同的亚硝基芳烃，我们在亚硝基苯和两个烯醇醚之间开发了金催化的 [2 + 2 + 1]-环化，以使用 1,4-环己二烯作为氢供体产生 5-烷氧基异恶唑烷。

• Hindered aryl bromides for regioselective palladium-catalysed direct arylation at less favourable C5-carbon of 3-substituted thiophenes
  作者：Rongwei Jin、Charles Beromeo Bheeter、Henri Doucet

  DOI：10.3762/bjoc.10.123

  日期：——

  3-substituted thiophene derivatives in favour of carbon C5. The coupling of this aryl bromide with a variety of 3-substituted thiophenes gave in all cases the desired 5-arylation products in moderate to good yields using only 0.5 mol % of a phosphine-free and air-stable palladium catalyst. Then, from these 5-arylthiophenes, a second palladium-catalysed C-H bond functionalization at C2 of the thiophene ring

  使用拥挤的芳基溴 2-溴-1,3-二氯苯作为偶联伙伴可以改变 3-取代噻吩衍生物芳基化的区域选择性，有利于碳 C5。该芳基溴化物与各种 3-取代噻吩的偶联在所有情况下均以中等至良好的产率得到所需的 5-芳基化产物，仅使用 0.5 mol% 的不含膦且空气稳定的钯催化剂。然后，从这些 5-芳基噻吩，在噻吩环的 C2 处进行第二个钯催化的 CH 键官能化，可以合成具有两个不同芳基单元的 2,5-二芳基噻吩。
