The use of palladium chloride as a precatalyst for the amination of aryl bromides is reported. To overcome the poor solubility of palladium chloride in commonly used solvents, a procedure was developed in which PdCl2 was preheated with neat amine in the presence of a phosphine ligand before the addition of the other reaction components. This protocol is effective for a broad range of substrate combinations using several types of phosphine ligands.
