No copping out! Copper(I) phenoxide complexes containing chelating ligands (see picture), proposed intermediates in copper‐catalyzed etherification of aryl halides, have been synthesized and fully characterized. The kinetic and chemical competence of the isolated complexes are demonstrated for the synthesis of aryl phenyl ethers, and experiments provide evidence against mechanistic pathways involving
无处遁形!含有螯合配体的苯酚铜(I)络合物(见图)是铜催化芳基卤化物醚化的中间体,已被合成并充分表征。分离的复合物的动力学和化学能力在芳基苯基醚的合成中得到了证明,实验提供了反对涉及形成自由基或笼状自由基的机制途径的证据。
