The first example of intermolecular C–H arylation of substituted 1H-indazoles is reported. Various 1-substituted indazoles were used as starting materials, and (hetero)aryl bromides and iodides were investigated as coupling partners. Different reaction conditions were investigated. The best results were obtained using Pd(OAc)2 as catalyst, 1,10-phenanthroline as ligand, K2CO3 as base, and DMA as solvent
报道了取代的 1H-吲唑的分子间 C-H 芳基化的第一个例子。各种 1-取代的吲唑被用作原料,(杂)芳基溴化物和碘化物作为偶联伙伴进行了研究。研究了不同的反应条件。使用 Pd(OAc)2 作为催化剂,1,10-菲咯啉作为配体,K2CO3 作为碱,DMA 作为溶剂获得了最好的结果。配体对取代的 1H-吲唑的 C-H 芳基化的关键作用得到强调。
