The bulky and electron-rich MOP-type ligand was efficient for the Pd-catalyzed amination of aryl tosylates. The in situ generated Pd(0) was a more efficient catalyst precursor than Pd(dba)(2). In the presence of Pd(OAc)(2), PhB(OH)(2), and a hindered and electron-rich MOP-type ligand, a variety of primary aryl amines reacted with various aryl tosylates to form the corresponding secondary aryl amines in high yields with high selectivity. Furthermore, the catalyst system was also efficient for the arylation of indoles and hydrazones with aryl tosylates.
