摘要
Aryl bromides are coupled to primary aliphatic amines, anilines and cyclic secondary amines in an efficient and selective procedure using catalytic amounts of Pd(OAc)(2) and the chelating ligand 9,9-dimethyl-4,6-bis(diphenylphosphino)xanthene (Xantphos). This catalyst system accomodating low catalyst loadings (0.5 mol % Pd) allows amination of both electron-poor and electron-rich aryl bromides. Even sterically crowded substrates show good reactivity.
