A 1,4-di(2,6-diisopropylphenyl)-1,2,3-triazol-5-ylidene (tzIPr)-based PEPPSI-type palladium complex was developed as an excellent precatalyst for the Suzuki–Miyaura cross-coupling reaction. The complex showed high activity under mild conditions for the cross-coupling reactions between various types of aryl chlorides and aryl boronic acids regardless of the steric and electronic nature of the substrates
开发了一种基于 1,4-二(2,6-二异丙基苯基)-1,2,3-三唑-5-亚基 (tzIPr) 的 PEPPSI 型钯配合物作为 Suzuki-Miyaura 交叉偶联反应的优异预催化剂. 无论底物的空间和电子性质如何,该配合物在各种类型的芳基氯化物和芳基硼酸之间的交叉偶联反应中都显示出温和条件下的高活性。
