Abstract

The in situ-generated nickel (0) species, presumably atomic nickel, from nickel (II) salt and zinc powder has been proved to be an effective catalyst for the Finkelstein-type displacement reaction of aryl bromides with potassium iodide to give aryl iodides under mild conditions. This species was also effective for the Ullmann-type coupling of bromides or aryl iodides by the use of zinc powder to give biaryls. Furthermore, in the presence of excess ...
