report a one-pot process that marries mechanistically distinct, traditional cross-coupling reactions with C-H functionalization using the same precatalyst. The reactions proceed in yields of up to 95%, in air, and require no extraneous ligand. The reactions are thought to be facilitated by harnessing the substrate quinoline as an N-ligand, and evidence of the palladium-quinoline interaction is provided
在本文中,我们报告了一个一锅法,该方法将机械上独特的传统交叉偶联反应与使用相同的预催化剂的CH官能化结合在一起。在空气中,反应以高达95%的产率进行,不需要多余的配体。认为通过利用底物喹啉作为N-配体可以促进反应,并且1H-15N HMBC NMR光谱学和X射线晶体学结构提供了钯-喹啉相互作用的证据。该方法的应用通过快速形成荧光的,π扩展的框架得以证明。
