Cu-catalyzed O-arylation of phenols with aryl iodides and bromides can be performed under mild condition in DMSO/K(3)PO(4) with use of picolinic acid as the ligand for copper. This method tolerates a variety of functional groups and is effective in the synthesis of hindered diaryl ethers and heteroaryl ethers.
在 DMSO/K3PO4中,使用吡啶甲酸作为铜的配体,在温和条件下,酚类化合物可以与芳基碘化物和溴化物进行铜催化的 O-芳基化反应。该方法对多种官能团具有耐受性,并且在受阻二芳基醚和杂芳基醚的合成中非常有效。
