General method of synthesis of 1,4,5-trisubstituted-1,2,3-triazoles by Suzuki-Miyaura cross-coupling from 4- and 5-halo-1,2,3-triazoles is reported. The reaction is mediated by expanded-ring N-heterocyclic carbene palladium complex in water. The developed reaction protocol meets the requirements of “green chemistry”. Cross-coupling of 4- and 5-chlorotriazoles is reported for the first time.
报道了通过Suzuki-Miyaura从4-和5-卤代-1,2,3-三唑的交叉偶联来合成1,4,5-三取代-1,2,3-三唑的一般方法。该反应由水中的扩环N-杂环卡宾钯配合物介导。开发的反应方案符合“绿色化学”的要求。首次报道了4-和5-氯三唑的交叉偶联。
