A combination of palladium and an imidazolium chloride has been used as catalyst precursor in the amination of aryl chlorides. The imidazolium salt IPrHCl (4, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) was found to provide the most efficient transformation rates in this catalytic system. This new system proves general and efficient for aryl chlorides as well as aryl bromides and iodides.
