| Abstract: | The Ullmann reaction of aryl halide or heteroaryl halide and imidazole catalyzed by amino methylene phosphonic acid resin-supported copper complex(abbreviated as APAR—Cu(Ⅱ)) was discussed.The results showed that the catalyst exhibited satisfactory activity when using DMSO as solvent and KOH as base at 120 ℃ and the corresponding coupling products were obtained in good yield between 67%~95% and the complex could be reused for several times. |
