Ammonia as Ultimate Amino Source in Synthesis of PrimaryAmines via Nickel-Promoted C–H Bond Amination

The direct use of ammonia in transition-metal promoted C–H bond amination for the synthesis of primary amines is considered to be one of the major challenges in synthetic organic chemistry. Herein, we report that such transformation can be successfully achieved via nickel-promoted amination of inert arene C–H bonds with ammonia gas assisted by an 8-amino-quinoline directing group.
