  TMP-碘鎓 (III) 乙酸盐的配体和抗衡离子辅助苯酚 O-芳基化

  摘要：

  实现了三甲氧基苯基 (TMP)-碘鎓 (III) 乙酸酯对苯酚O-芳基化的高反应性。首先确定 TMP 配体和乙酸根阴离子协同增强对苯酚氧原子的亲电反应性。与先前报道的技术相比，所提出的方法以显着更高的产率提供了获得各种二芳基醚的途径。在O-芳基化过程中可以耐受各种官能团，包括脂肪醇、硼酸酯和空间位阻基团，验证了这种配体和抗衡离子辅助策略的适用性。

• Trimethoxyphenyl (TMP) as a Useful Auxiliary for <i>in situ</i> Formation and Reaction of Aryl(TMP)iodonium Salts: Synthesis of Diaryl Ethers
  作者：Rory T. Gallagher、Souradeep Basu、David R. Stuart

  DOI：10.1002/adsc.201901187

  日期：2020.1.23

  Herein, we describe a synthetic approach for arylation that exploits the in situ formation and reaction of an unsymmetrical diaryliodonium salt. In this way, aryl iodides are used as reagents in a metal‐free reaction with phenols, and a trimethoxyphenyl (TMP) group is used as a “dummy” group to facilitate transfer of a wide range of aryl moieties. The scope of aryl electrophiles and phenol nucleophiles

  在这里，我们描述了一种芳基化的合成方法，该方法利用了不对称二芳基碘鎓盐的原位形成和反应。通过这种方式，芳基碘化物在与酚的无金属反应中用作试剂，三甲氧基苯基（TMP）基团用作“虚拟”基团，以促进各种芳基部分的转移。芳基亲电试剂和苯酚亲核试剂的范围很广（> 30个例子），收率很高（平均52-95％，平均80％）。单锅偶联反应避免了二芳基碘鎓盐的合成，并为后续反应和新颖的化学选择性提供了机会。
