采用一种新型的4-羟基吡啶甲酰胺配体, 成功地完成了之前难以反应的芳基氯化物和苯基亚磺酸钠的铜催化偶联, 这代表着这两类底物的第一次金属催化的偶联反应. 反应在130 ℃下进行, 生成二芳基砜, 收率在53%~96%. 底物可以兼容各种电性的芳基氯和杂芳基氯.

关键词: 偶联反应, 铜催化, 配体, 芳基氯代物, 二芳基砜

By using a newly developed 4-hydroxy picolinohydrazide as the ligand, Cu-catalyzed coupling of (hetero)aryl chlorides with sodium aryl sulfonates proceeded smoothly at 130 ℃ to give a series of biarylsulfones in 53%~96% yields. This represents the first metal-catalyzed coupling reaction of (hetero)aryl chlorides with sodium aryl sulfonates. Aryl and heteroaryl chlorides bearing either electron-donating or electron-withdrawing groups were applicable for this coupling reaction.

Key words: coupling reaction, copper catalysis, ligand, (hetero)aryl chloride, biarylsulfone
