It doesn′t cost a dime: A nickel-based system that catalyzes the aromatic amination of aryl chlorides is presented. Starting from a simple Ni(II) salt, aliphatic phosphonium-based ionic liquids (ILs) were found to stabilize the nickel nanoparticles formed in situ during the reaction. The IL also enables successful recycling of the system after the reaction.
