one-pot process involving cascade C-H activation and insertion between amidines and alkynes in the presence of palladium salt is described. With this methodology, various novel eight-membered cyclopalladated amidines were efficiently constructed. Notably, a series of functionalities with potential application were readily accommodated under the reaction conditions. Isotope effects and H/D exchange
描述了一种一锅法,该方法涉及在钯盐存在下级联CH活化和am与炔之间的插入。用这种方法,可以有效地构建各种新颖的八元环palpalated idine。值得注意的是,在反应条件下容易适应一系列具有潜在应用的功能。同位素效应和H / D交换表明,这种级联反应是由am的N-苯基环中的邻位CH键断裂而引发的。
