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.
