We report the first room-temperature direct C-2 arylation of indoles with iodoarenes by using a highly electrophilic palladium catalyst generated in situ from Pd(OAc)2 and a silver carboxylate. These mild conditions permit a broad set of functionalities both in the indole and in the aryl iodide units such as free alcohols, phenols, aldehydes, bromides, or nitriles, thus allowing the synthesis of a
我们报道了使用由 Pd(OAc)2 和羧酸银原位生成的高亲电子性钯催化剂,首次在室温下将吲哚与碘芳烃直接 C-2 芳基化。这些温和的条件允许在吲哚和芳基碘单元(如游离醇、酚、醛、溴或腈)中具有广泛的官能团,从而允许以优异的产率合成各种新型化合物。
