A suzuki cross-coupling reaction of aryltrimethylammonium triflates based on an IMes·Ni(0) catalyst system tolerates a wide range of electron-withdrawing and electron-donating substituents on both coupling partners. This methodology constitutes a novel, mild method to activate anilines for metal-catalyzed cross-coupling reactions.
