Ethylene trimerisation and tetramerisation catalysts with polar-substituted diphosphinoamine ligands.
Chromium-based catalyst systems with polar-substituted diphosphinoamine ligands are selective for either trimerisation or tetramerisation of ethylene, depending on the position of the polar groups on the aryl rings.
