The invention relates to compounds in which a transition metal is complexed with two ligand systems and the two systems are reversibly interlinked by at least one bridge from a donor and an acceptor, and at least one substituent on the acceptor group is a fluorinated aryl group. The invention also relates to the use of the inventive compounds as catalysts and to a method for polymerizing olefins.
La présente invention concerne des composés dans lesquels un métal de transition est complexé avec deux systèmes de ligands, et ces deux systèmes sont reliés l'un à l'autre de manière réversible par l'intermédiaire d'au moins un pont composé d'un donneur et d'un accepteur, au moins un substituant du groupe accepteur étant un reste aryle fluoré. L'invention concerne également l'utilisation de ces composés en tant que catalyseurs, ainsi qu'un procédé de polymérisation d'oléfines.
