found to be an excellent ligand for copper-catalyzed N-arylation of azoles and amides with aryl halides under mild conditions. The reaction took place at 82 °C in MeCN with broad functional-group compatibility. A combination of the ligand and CuI proved to be an efficient catalytic system to promote the coupling reactions of aryl halides with azoles and amides.
(E)-3-(二甲氨基)-1-(2-羟基苯基)prop-2-en-1-one 被发现是铜催化的唑类和酰胺与芳基卤化物在温和条件下 N-芳基化的极好配体. 该反应在具有广泛官能团兼容性的 MeCN 中于 82°C 下进行。配体和CuI的组合被证明是促进芳基卤化物与唑类和酰胺偶联反应的有效催化体系。
