A breakthrough in ligand chemistry has led to the development of a new catalyst to synthesize the aromatic amines that are central building blocks in many drugs, pesticides and fine chemicals, report scientists at Ruhr-Universität Bochum (RUB), Bochum, Germany.Currently, the manufacture of aromatic amines involves reacting primary or secondary amines with ring-shaped aryl halides in the presence of a palladium catalyst. These reactions often rely on electron-rich phosphine ligands to stabilize the palladium. So, for example, commercially important phosphines such as cataCXium and DalPhos contain different electron-donating groups within them.Unfortunately, the finite…
