  摘要：

  AbstractWe report the the copper(II) acetoacetonate [Cu(acac)2]/BINAP‐catalyzed synthesis of arylamines from N‐tosylhydrazones and anilines. A fine tuning of the reaction conditions was required to accomplish the cross‐coupling successfully, including the ligands effect and the addition of small amounts of water. The characteristic feature of this protocol is its functional group compatibility and its chemoselectivity when various aminophenol derivatives were used. Taking into consideration the interest for this copper‐reductive coupling in which no stoichiometric metal hydride reagent is employed, this can be considered as an alternative to the conventional reductive amination.magnified image

  highly active and chemoselective manganese catalyst for the hydrogenation of imines. The catalyst has a large scope, can reduce aldimines and ketimines, and tolerates a variety of functional groups, among them hydrogenation sensitive examples such as an olefin, a ketone, nitriles, nitro groups and an aryl iodo substituent or a benzyl ether. We could investi-gate the transfer step between imines and the

  我们介绍了一种用于亚胺加氢的高活性和化学选择性锰催化剂。该催化剂适用范围广，可还原醛亚胺和酮亚胺，可耐受多种官能团，其中对氢化敏感的例子如烯烃、酮、腈、硝基和芳基碘取代基或苄基醚。我们可以详细研究亚胺和氢化物配合物之间的转移步骤。我们发现配体的双重去质子化是必不可少的，过量的碱不会导致转移步骤中的更高速率。我们将实际的加氢催化剂鉴定为 K-Mn-双金属物种，并且可以通过 X 射线分析获得氢化物转移后形成的 K-Mn 配合物的结构。核磁共振实验表明氢化物转移是一个明确定义的反应，这是亚胺的一级，双金属（K-Mn）氢化物的一级，并且速率与钾碱的浓度无关。我们提出了一种外球机制，其中质子似乎不参与速率确定步骤，导致底物中的瞬态带负电荷的氮原子与 HOtBu（2-methylpropan-2-ol）迅速反应以产生胺。这是基于几个观察结果，例如反应速率不依赖于 HOtBu 浓度，没有可观察到的锰酰胺
