Regioselectively substituted indoles are prepared by a Pd‐catalyzed CC/CN bond‐forming sequence from imines and o‐dihaloarenes or o‐haloarene sulfonates. The heterogeneous reaction as a suspension in water and under microwave heating offers important advantages in comparison with the conventional reaction in an organic solvent, among them, operational simplicity, the employment of KOH solutions instead
区域选择性取代的吲哚通过Pd催化的C中制备 C / C N键形成序列从亚胺和ö -dihaloarenes或ö -haloarene磺酸盐。与在有机溶剂中的常规反应相比,在水中和微波加热下作为悬浮液的非均相反应具有重要的优势,其中包括操作简便,使用KOH溶液代替醇盐以及显着减少反应时间。
