olefinations exclusively at the C-3- or C-8-positions in the quinoline framework has been developed by catalyst control. Distal C(3)-H functionalization is achieved by using palladium catalysis, whereas proximal C(8)-H functionalization is obtained by employing ruthenium catalysis. Switching the site selectivity within a single substrate directly indicates two diverse pathways, which are operating under the
通过催化剂控制,已经开发出一种独特的方法,其仅在
喹啉骨架的C-3-或C-8-位上实现位点选择性CH烯烃聚合。远端C(3)-H功能化是通过使用
钯催化实现的,而近端C(8)-H功能化是通过使用
钌催化实现的。在单个基质中切换位点选择性直接表明了两种不同的途径,它们在
钯和
钌催化的反应条件下运行。
