Room‐Temperature Copper‐Catalyzed Carbon–Nitrogen Coupling of Aryl Iodides and Bromides Promoted by Organic Ionic Bases

Good solubility alone does not explain the performance of organic ionic bases in the room-temperature coupling of aryl iodides and even bromides with aliphatic and aromatic amines and N-heterocycles (NuH; see scheme). Conductivity measurements show that these organic ionic bases, which contain tetraalkylammonium or -phosphonium cations, are readily ionized in organic solvents.
