Rapid and concise: The title reaction proceeds via copper complexes in a highly stereospecific manner (see scheme; acac=acetylacetonate, phen=1,10‐phenanthroline, TBS=tBuMe2Si). The catalysis provides a rapid and concise route to allylarenes that contain fluorinated aromatic cores of an electron‐deficient nature.
快速简明:标题反应以高度立体定向的方式通过铜络合物进行(参见方案; acac =乙酰丙酮酸酯,phen = 1,10-菲咯啉,TBS = t BuMe 2 Si)。催化作用提供了一条快速而简明的途径,以得到含有电子不足性质的氟化芳族核的烯丙基芳烃。

A palladium-catalyzedallylic C–H arylation reaction with electron-deficient arenes with high regio- and stereoselectivity is reported. This work represents the first successful use of 1,1′-bi-2-naphthol as the ancillary ligand in allylic C–H activation, which is the key factor for chemoselectivity. Furthermore, high selectivity allylic C–H acetoxylation and amination were also successfully achieved
