The present invention relates to an injection system for injecting material into a receiving vessel, said injection system comprising: (i) an injection chamber provided with means to connect to the receiving vessel, and (ii) an injection capsule, adapted to fit within the injection chamber, and comprising a reservoir for the material and a valve, said injection system being adapted so that opening of the valve causes material contained within the reservoir to be injected into the receiving vessel by action of a pressure differential between the injection chamber and the receiving vessel. The present invention also relates to a method of injecting material into a receiving vessel using said injection system.

The invention relates to a bidentate phosphine ligand, the phosphorus atoms of the phosphine being connected via a bridge group, 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 phosphorus 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.
