An efficient and general protocol for the decarboxylative cross-coupling of pyridazine-3-carboxylicacids with aryl-bromides has been described. This method provides a new avenue for the synthesis of 3-arylpyridazines via decarboxylative cross-coupling strategy by employing the dual-catalyst system of Pd(PPh3)4/Cu2O in the presence of Li2CO3 at 160 °C in DMA.
已经描述了哒嗪-3-羧酸与芳基溴化物的脱羧交叉偶联的有效且通用的方案。该方法为Pd(PPh 3)4 / Cu 2 O的双催化剂体系在160℃下Li 2 CO 3存在下通过Pd(PPh 3)4 / Cu 2 O双催化剂体系的合成提供了一种新的途径。 DMA。
