Rhodium acetate effectively promotes the carboxylate‐directed ortho‐arylation of (hetero)aromatic carboxylates with aryl bromides. The main advantage of this phosphine‐free, redox‐neutral method arises from its efficiency in assembling biologically meaningful electron‐rich arylpyridines, which are problematic substrates in known C−H arylations using Pd, Ru, and Ir catalysts.
乙酸铑有效地促进了(杂)芳族羧酸盐与芳基溴化物的羧酸盐定向邻位芳基化。这种无膦,氧化还原中性方法的主要优点来自于它在组装具有生物学意义的富电子芳基吡啶方面的效率,这些芳基吡啶是已知的使用Pd,Ru和Ir催化剂在CH芳基化中存在问题的底物。
