A catalytic defluorinativeboroarylation of alkenes with polyfluoroarenes and B2pin2 with the assistance of a PCy3-ligated copper catalyst was developed. Taking advantage of bench-stable alkenes as latent nucleophiles and avoiding traditional reliance on stoichiometric quantities of organometallics, this method showcased good functional group compatibility and proceeded under very mild reaction conditions
在 PCy 3配位铜催化剂的帮助下,开发了烯烃与多氟芳烃和 B 2 pin 2的催化脱氟硼芳基化反应。利用稳定的烯烃作为潜在的亲核试剂,避免传统上对有机金属化学计量数量的依赖,该方法展示了良好的官能团相容性,并在非常温和的反应条件下进行。高效地制备了一系列有价值的含硼多氟芳烃,包括含全碳季碳中心的三芳基烷基硼酸酯,否则难以获得。
Copper‐Catalyzed Defluorinative Hydroarylation of Alkenes with Polyfluoroarenes
A catalytic defluorinative hydroarylation of alkenes with polyfluoroarenes in the presence of dppbz‐ligated Cu catalyst and silanes was developed. This method provides a straightforward and alternative avenue to synthetic important polyfluorinated arenes with readily available and bench‐stable alkenes as latent nucleophiles, and therefore avoids conventional reliance on stoichiometric quantities of
