Abstract

The cross-coupling of bromomagnesium diarylamides, generated in situ from diarylamines, with aryl bromides or iodides can be effected with a simple NiCl₂(PPh₃)₂−PPh₃ catalyst system under relatively mild conditions. This coupling reaction is an inexpensive, convenient, and practical method, functioning as an alternative to the corresponding Pd-catalyzed or Cu-mediated process for the synthesis of triarylamines.
