activation of fluorinated alkenes and arenes was developed. In this Pd-catalyzed Suzuki–Miyaura-type cross-coupling reaction, neither a base for enhancing the reactivity of the organoboron reagents nor a Lewis acid for promoting C–F bond activation was required. A fluoropalladium intermediate played an essential role in this reaction. In addition, a Ni(NHC) catalyst was efficient for C–C coupling through
开发了一种通过氟化烯烃和芳烃的 C-F 活化与有机硼酸酯形成 C-C 键的新策略。在这种 Pd 催化的 Suzuki-Miyaura 型交叉偶联反应中,既不需要用于增强有机硼试剂反应性的碱,也不需要用于促进 C-F 键活化的路易斯酸。氟钯中间体在该反应中发挥了重要作用。此外,Ni(NHC)催化剂通过氟芳烃的C-F键活化对C-C偶联是有效的。
