[reaction: see text] Immobilization of copper onto modified Wang resin provided a polymer-supported copper catalyst, which is effective in cross-coupling reactions between N- or O-containing substrates and arylboronic acids. The copper catalyst is air stable and can be recycled with minimal loss of activity.

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。
