title: Chromium-catalysed ethene trimerisation and tetramerisation--breaking the rules in olefin oligomerisation.
abstract: The discovery of a new generation of highly active and selective ethene trimerisation and tetramerisation catalysts has radically changed the field of olefin oligomerisation. This Frontiers article gives an overview of these recent advances.
