A selective palladium-catalyzed Suzuki–Miyaura coupling reaction of polyfluorophenyl oxazolines through ortho C–F activation is described. It was found that reactions with DPPF as the ligand occurred much faster than those with other ligands. A variety of arylboronic acids including challenging functionalized arylboronic acids such as enolizable ketones, aldehyde, cyano, ester, and trifluoromethyl
描述了通过邻位CF活化对多氟苯基恶唑啉的选择性钯催化的Suzuki-Miyaura偶联反应。发现以DPPF作为配体的反应发生得比与其他配体的反应快得多。在反应条件下可以耐受各种芳基硼酸,包括具有挑战性的官能化芳基硼酸,例如可烯醇化的酮,醛,氰基,酯和三氟甲基。
