We have introduced a novel, efficient, commercially available and economically attractive N-donor tripod ligand, tris-(2-aminoethyl)amine for copper-catalyzed Ullmann diaryl ether synthesis. This catalyst system is highly active for both aryl iodides and aryl bromides. Variously substituted diaryl ethers have been synthesized in good to excellent yields.
我们已经介绍了一种新颖,有效,可商购且在经济上有吸引力的N供体三脚架配体tris-(2-氨基乙基)胺,用于铜催化的Ullmann二芳基醚合成。该催化剂体系对芳基碘化物和芳基溴化物都具有高活性。已经以良好至优异的产率合成了各种取代的二芳基醚。
