  日期：——

  Diaryl ethers containing condensed polycyclic aryl groups were synthesized from arenols in the presence of a catalytic amount of p-chlorobenzenesulfonic acid. Symmetrical binaphthyl, biphenanthryl, and bipyrenyl ethers were obtained in high yields. Unsymmetrical derivatives were also synthesized from 9-phenanthrol and arenols, using combinations of reactive and unreactive substrates.

• Nickel-Catalyzed Homocoupling of Aryl Ethers with Magnesium Anthracene Reductant
  作者：Kosuke Higashida、Masaya Sawamura、Vishal Kumar Rawat

  DOI：10.1055/a-1509-5954

  日期：2021.9

  Nickel-catalyzed reductive homocoupling of aryl ethers has been achieved with Mg(anthracene)(thf)3 as a readily available low-cost reductant. DFT calculations provided a rationale for the specific efficiency of the diorganomagnesium-type two-electron reducing agent. The calculations show that the dianionic anthracene-9,10-diyl ligand reduces the two aryl ether substrates, resulting in the homocoupling

  已使用 Mg(蒽)(thf)3 作为容易获得的低成本还原剂实现了芳醚的镍催化还原均偶联。DFT 计算为二有机镁型双电子还原剂的特定效率提供了基本原理。计算表明，双阴离子蒽-9,10-二基配体还原了两个芳基醚底物，通过向Ni-Mg双金属体系提供电子导致均偶联反应形成有机镁镍(0)-ate配合物，从而导致两个连续的 C-O 键断裂反应。计算还表明路易斯酸性镁原子和富电子镍原子在 C-O 裂解反应中的协同作用。
