The Werner salt [Ni(NH3)6]Cl2 can be used as both a nitrogen and a catalytic nickel source that allow for the efficient amination of aryl chlorides in the presence of a catalytic amount of bipyridine ligand under the irradiation of 390–395 nm light without the need of any additional catalysts, solving the problem of easy deactivation and difficult recovery of transition metal nickel catalysts.
