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
