derivatives with peresters in the presence of [Ru(p-cymene)Cl2]2 has been developed. The combination of ruthenium(II), AgBF4, CoI2, and 2,2,6,6-tetramethyl-1-piperidinyloxy is found to be an effective catalytic system to provide various biaryl compounds in satisfactory yields within minutes. Notably, steric hindrance is a very important determinant of the reaction.
开发了一种在 [Ru( p -cymene)Cl 2 ] 2存在下,1-(1-naphthalen-1-yl)isoquinoline 衍生物与过酸酯的新型 C–H 酰氧基化方法。发现钌 (II)、AgBF 4、CoI 2和 2,2,6,6-四甲基-1-哌啶基氧基的组合是一种有效的催化体系,可在几分钟内以令人满意的收率提供各种联芳基化合物。值得注意的是,空间位阻是反应的一个非常重要的决定因素。
