Cu-catalyzed O-arylation of phenols with aryl iodides and bromides can be performed under mild condition in DMSO/K3PO4 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 hindereddiaryl ethers and heteroaryl ethers.
铜催化苯酚与芳基碘化物和溴化物的 O-芳基化反应可以在温和条件下在 DMSO/K 3 PO 4 中进行,使用吡啶甲酸作为铜的配体。该方法耐受多种官能团,在受阻二芳基醚和杂芳基醚的合成中有效。
Decarbonylative Diaryl Ether Synthesis by Pd and Ni Catalysis
Because diarylethers are present as an important motif in pharmaceuticals and natural products, extensive studies for the development of novel methods have been conducted. A conventional method for the construction of the diarylether moiety is the intermolecular cross-coupling reaction of aryl halides and phenols with a copper or palladium catalyst. We developed a catalytic decarbonylative etherification
