A wide range of N-arylated indoles are selectively synthesized through intermolecular C(aryl)–N bond formation from the corresponding aryl iodides and indoles through Ullmann-type coupling reactions in the presence of a catalytic amount of easily available N,N,N′,N′-tetramethyl-BINAM–CuI complex under very mild reaction conditions.
广泛的Ñ -arylated的吲哚通过分子间C(芳基)-N键从通过乌尔曼型相应的芳基碘化物和吲哚中的催化量的存在下偶联反应形成选择性合成容易获得Ñ,Ñ,Ñ ' ,ñ ' -四甲基BINAM翠复杂下非常温和的反应条件。
