The first Suzuki cross-coupling reaction of aryltrimethylammonium triflates based on the use of an IMes.Ni(0) catalyst system is described. A wide range of electron-withdrawing and electron-donating substituents are tolerated on both the aryltrimethylammonium triflate and the boronicacid components of this reaction. In addition to arylboronic acids, the scope of the reaction is extended to encompass
A nickel-catalyzed, efficient C-N bond reduction of aromatic and benzylic ammonium triflates has been developed using sodium isopropoxide as a reducing agent. The high efficiency, mild conditions, and nice compatibility...

cobalt-catalyzed aminocarbonylation of aniline-derived trialkylammoniumsaltspromoted by visiblelight via a challenging C(sp2)−N cleavage. The reaction is suitable for late-stage functionalization and is amenable to telescoped carbonylations directly from anilines. Mechanistic studies and DFT calculations support a novel mechanism involving a key visible light-induced carbonyl photodissociation and SNAr-type
