We report a new approach to synthesize palladium complexes through Ag₂O-promoted hydrolytic ring opening followed by palladium coordination. The novelty of Ag₂O-promoted hydrolysis in comparison with the commonly used base-mediated hydrolysis lies in the anion-controlled product selectivity in the synthesis of pincer-type palladium complexes. Moreover, these palladium complexes have been tested in the Suzuki reaction using aryl bromides in methanol and H₂O, respectively. In comparison with palladium complexes with normal coordination, the palladium complexes generated from the hydrolytic ring-opening coordination demonstrate excellent catalytic activity.

阴离子控制的Ag ₂ O介导的苯并咪唑鎓开环及其在钯钳型配合物合成中的应用

我们报告了一种新的方法，通过Ag ₂ O促进的水解开环，然后由钯配位来合成钯配合物。与常用的碱介导的水解相比，Ag ₂ O促进的水解的新颖之处在于在钳型钯配合物的合成中阴离子控制的产物选择性。此外，这些钯配合物已分别在甲醇和H ₂ O中的芳基溴化物的Suzuki反应中进行了测试。与具有正常配位的钯配合物相比，由水解开环配位产生的钯配合物表现出优异的催化活性。
