  Catalytic C–H bond arylation of aryl imines and oxazolines in water with ruthenium(II)-acetate catalyst

  摘要：

  Ruthenium(II)-acetate catalyzed C-H bond activation/diarylations of aryl-aldimines, aryl-ketimines and phenyl-oxazolines with aryl bromides in water are reported. Water strongly favours the catalytic diarylation of aryl-ketimines and phenyl-oxazolines with respect to organic solvent. CD (C) 2012 Elsevier Ltd. All rights reserved.

• Cobalt-Catalyzed C−H Functionalizations by Imidate Assistance with Aryl and Alkyl Chlorides
  作者：Ruhuai Mei、Lutz Ackermann

  日期：2016.7.28

  inexpensive cobalt(II) acetylacetonate [Co(acac)2] and an N‐heterocyclic carbene (NHC) ligand enabled versatile C−H arylations by oxazoline assistance. The broadly applicable, low‐valent cobalt catalyst displayed a wide substrate scope, and even proved applicable to challenging C−H alkylations with β‐hydrogen‐containing primary and secondary alkyl chlorides. The power of the cobalt‐catalyzed C−H arylation

  包含廉价的乙酰丙酮钴（II）[Co（acac）2 ]和N-杂环卡宾（NHC）配体的催化体系能够通过恶唑啉辅助实现多种CH芳基化反应。广泛适用的低价钴催化剂具有广泛的底物范围，甚至证明适用于具有挑战性的含β-氢的伯和仲烷基氯的CH烷基化反应。钴催化的CH芳基化协议的功能尤其体现在室温下23°C的CH H的活化以及高效的后期多样化，从而获得了具有生物活性的联芳基。
