Patent

CA 2189569

The invention relates to a bidentate phosphine ligand, the phosphorous atoms of the phosphine being connected via a bridge the bridge group of the bidentate phosphine ligand consisting of an ortho-anellated annular system, comprising two aryl groups, which aryl groups are connected by two bridges, the first bridge consisting of an -O- or an -S- atom and the second bridge being a group that contains an oxygen, sulphur, nitrogen, silicon or carbon atom or a combination of these atoms, the two phosphorous atoms being connected to the two aryl groups of the bridge group at the ortho-position relative to the -O- or -S- atom of the first bridge. The invention also relates to the use of this bidentate phosphium ligand in a catalyst system comprising also a transition metal compound which is used in the following type of reactions: hydroformylation, hydrogenation, hydrocyanation, polymerization, isomerisation, carboxylation, cross coupling and metathesis.

Ligand de phosphine bidentée, les atomes de phosphore de la phosphine étant liés par l'intermédiaire d'un groupe de pontage constitué d'un système annulaire ortho-anellé, comportant deux groupes aryles liés par deux ponts dont le premier est constitué d'un atome -O- ou -S- tandis que le second est un groupe contenant un atome d'oxygène, de soufre, d'azote, de silicium ou de carbone ou une association de ces atomes, les deux atomes de phosphore étant liés aux deux groupes aryles du groupe de pontage en position ortho par rapport à l'atome -O- ou -S- du premier pont. On a également prévu l'utilisation de ce ligand de phosphine bidentée dans un système catalyseur, comportant également un composé de métal de transition, utilisé dans les réactions suivantes: hydroformylation, hydrogénation, hydrocyanation, polymérisation, isomérisation, carboxylation, réticulation et métathèse.
