Abstract A simple and efficient strategy for the C–N cross-coupling of indazole with a variety of substituted aryl bromides is reported. Under the optimized conditions, a broad scope of N-arylated products were obtained in good to excellent yields (up to 87%) under the ligand-free conditions.
摘要 据报道,一种简单有效的方法使吲唑与各种取代的芳基溴化物进行C–N交叉偶联。在最优化的条件下,在无配体的条件下,可以以良好至极好的收率(高达87%)获得宽范围的N-芳基化产物。
