  钯催化芳基氯和芳基溴化物与铵盐的胺化

  摘要：

  我们报道了钯催化的芳基卤化物与氨和气态胺作为铵盐的偶联。芳基氯和邻位取代的芳基溴与硫酸铵偶联形成苯胺，与二恶烷中的氨偶联相比，对伯芳胺的选择性高于对二芳胺的选择性。芳基氯反应的静止状态与芳基溴反应的静止状态不同，并且提出这种静止状态的变化是为了解释两种卤代芳烃的反应选择性的差异。

  新的5-取代的苯并[ b ]噻吩衍生物的合成

  摘要：

  我们小组以前的工作涉及1-（芳基）-3- [4-（芳基）哌嗪-1-基]丙烷衍生物的合成，以寻找具有双重作用方式的新型高效抗抑郁药：5-羟色胺再摄取抑制和5-HT 1A受体的亲和力[1-4]。从这些研究中我们得出结论，3- [4-（芳基）哌嗪-1-基] -1-（苯并[ b ]噻吩-3-基）丙烷衍生物导致了最佳结果。该研究项目的继续，需要制备一些新的3-酰基-5-取代的苯并[ b ]噻吩，其在5位上具有广泛的取代基，范围从硝基到羟基衍生物。为了获得这些衍生物，我们尽可能地将相应的5-取代的苯并[ b ]噻吩酰化。

  Pd‐catalyzed Hiyama vinylation reaction of non‐activated aryl chlorides and bromides under mild conditions was developed. The use of efficient vinyl donors and electron‐rich sterically hindered phosphine ligands was critical for the success of the reaction. The products of this transformation can be used for Am/Cm separation, an important challenge in nuclear fuel reprocessing. The substituent effect
