• Ruthenium-Catalyzed Conjugate Hydrogenation of α,β-Enones by in situ Generated Dihydrogen from Paraformaldehyde and Water
  作者：Wanfang Li、Xiao-Feng Wu

  DOI：10.1002/ejoc.201403359

  日期：2015.1

  Notwithstanding that the highly selective hydrogenation of α,β-enones to allylic alcohols can be realized by using Noyori's Ru bifunctional system, the selective reduction of the C=C bonds in α,β-enones without touching the C=O bonds still lacks a general, simple, and efficient procedure. Ruthenium-catalyzed conjugate hydrogenation of various α,β-enones to saturated ketones with high selectivity was investigated

  尽管使用 Noyori 的 Ru 双功能系统可以实现 α,β-烯酮向烯丙醇的高度选择性氢化，但在不接触 C=O 键的情况下选择性还原 α,β-烯酮中的 C=C 键仍然缺乏通用、简单、高效的程序。研究了钌催化的各种α,β-烯酮以高选择性共轭氢化成饱和酮。该程序最重要的特点是由多聚甲醛（或福尔马林）和水原位产生的氢气用作还原剂。

  an excellent chemoselectivity profile using air-, moisture-insensitive and easy-to-handle nickel precatalysts. Our results render our method a powerful alternative, practicality and novelty aside, to commonly used organic halides as counterparts in carboxylation protocols. Furthermore, this study shows, for the first time, that traceless directing groups allow for the reductive coupling of substrates

  近年来，芳基卤化物和苄基卤化物与 CO2 的羧化取得了重大进展，成为使用化学计量量明确的金属物质的方便替代品。然而，这些过程中的大多数都需要使用自燃和空气敏感试剂，目前的方法主要限于有机卤化物。因此，非常希望发现一种温和的、操作简单的替代羧化反应，该羧化反应在广泛的底物范围内使用容易获得的偶联伙伴发生。在此，我们报告了一种新的协议，该协议涉及 CO2 协同活化的开发和惰性 C(sp(2))-O 和 C(sp(3))-O 键的相当具有挑战性的活化，这些键源自简单且廉价的酒精，这是该领域以前未被认识到的机会。这种前所未有的羧化事件的特点是其简单、温和的反应条件、显着的选择性模式以及使用对空气、水分不敏感且易于处理的镍预催化剂的优异化学选择性曲线。我们的结果使我们的方法成为一种强大的替代方案，实用性和新颖性，可以替代常用的有机卤化物作为羧化方案中的对应物。此外，这项研究首次表明，无痕导向基团允许在没有扩展
