  氧亲核试剂与二芳基碘鎓盐的无金属芳构化

  摘要：

  苯酚和羧酸可被二芳基碘鎓盐有效地芳基化。反应条件温和，不含金属，避免使用卤化溶剂，添加剂和过量试剂。经过短时间的反应，产品的收率就达到了优异的水平。在亲核试剂和二芳基碘鎓盐中，对立体障碍的耐受性都很好。范围包括邻和卤素取代的产品，很难通过金属催化的方法获得。可以容忍许多官能团，包括羰基，杂原子和烯烃。可以化学选择性地利用不对称盐获得具有迄今未报道的水平拥挤水平的产物。芳基化作用已经扩展到磺酸，可以通过两种不同的方法将其转化为磺酸酯。随着对二芳基碘鎓盐的有效合成方法的最新进展，该试剂现在便宜且容易获得。由碘鎓试剂形成的碘芳烃副产物可以定量回收，并用于再生二芳基碘鎓盐，从而改善了原子经济性。

• Metal-Free Synthesis of Aryl Ethers in Water
  作者：Erik Lindstedt、Raju Ghosh、Berit Olofsson

  DOI：10.1021/ol402960f

  日期：2013.12.6

  arylation of allylic and benzylic alcohols with diaryliodonium salts is reported. The reaction yields alkyl aryl ethers under mild and metal-free conditions. Phenols are arylated to diaryl ethers in good to excellent yields. The reaction employs diaryliodonium salts and sodium hydroxide in water at low temperature, and excess amounts of the coupling partners are avoided.

  据报道，烯丙基和苄基醇与二芳基碘鎓盐具有第一芳基化作用。该反应在温和且无金属的条件下产生烷基芳基醚。苯酚以良好或优异的产率芳基化为二芳基醚。该反应在低温下在水中使用二芳基碘鎓盐和氢氧化钠，避免了过量的偶合伴侣。

  The first synthesis of unsymmetric diaryliodonium salts directly from iodine and arenes is presented. The methodology provides diaryliodonium salts with the trimethoxyphenyl (TMP) moiety as dummy group. The protocol avoids the customary use of iodoarenes, which can be both expensive and toxic. Excess reagents are not required, and the reactions are performed under mild conditions. O-Arylations with

  提出了直接由碘和芳烃直接合成不对称二芳基碘鎓盐的方法。该方法提供了以三甲氧基苯基（TMP）部分为假基团的二芳基碘鎓盐。该方案避免了碘代芳烃的常规使用，碘代芳烃既昂贵又有毒。不需要过量的试剂，并且反应在温和的条件下进行。这些TMP盐的O-芳基化显示出高度的化学选择性。
• Room Temperature, Metal-Free Synthesis of Diaryl Ethers with Use of Diaryliodonium Salts
  作者：Nazli Jalalian、Eloisa E. Ishikawa、Luiz F. Silva、Berit Olofsson

  DOI：10.1021/ol200265t

  日期：2011.3.18

  A fast, high-yielding synthesis of diaryl ethers with use of mild and metal-free conditions has been developed. The scope includes bulky ortho-substituted diaryl ethers, which are difficult to obtain by metal-catalyzed protocols. Halo-substituents, racemization-prone amino acid derivatives, and heteroaromatics are also tolerated. The methodology is expected to be of high utility in the synthesis of complex molecules and in the pharmaceutical industry.
