An improved protocol was described for the amination of chloroarenes with diarylamines under NiCl2(PCy3)2 catalysis in the presence of a Grignard reagent as base. This method fully suits bromo-/iodoarene substrates as well, and even is expanded to certain aryl tosylates. A preliminary investigation into the mechanism suggests that this amination reaction might proceed through NiI and NiIII intermediates rather than via the usually expected Ni0-Ni II cycle.

Third times a charm: A new Pd-NHC catalyst, Pd-PEPPSI-IPentCl, has been developed for applications in amination reactions for the preparation of triarylamines. The catalyst can be used under mild conditions (carbonate base/dioxane, 80 °C) to perform multiple aminations in sequence from simple aniline derivatives that contain highly base-sensitive functional groups.
