We report here a two-in-one strategy for the Pd(II)-catalyzed tandem C–H arylation/decarboxylative annulation between readily available cyclic diaryliodonium salts and benzoic acids. The carboxylic acid functionality can be used as both a directing group for the ortho-C–H arylation and the reactive group for the tandem decarboxylative annulation. By a step-economical double cross-coupling annulation
我们在这里报告了一种二合一策略,用于在易于获得的环状二芳基碘鎓盐和苯甲酸之间进行Pd(II)催化的串联CH芳基化/脱羧环化反应。羧酸官能团既可以用作邻-C-H芳基化的直接基团,也可以用作串联脱羧环化的反应基团。通过分步经济的双交叉耦合环化程序,可以有效地构建特权的三亚苯基骨架,这在材料化学中具有潜在的应用。
