- SYNTHESIS AND CHEMISTRY OF THE PHENOXASILINS AND DIHYDRO-DIBENZO-OXASILEPINS
-
Formation of both sila-functional and carbo-functional phenoxasilins from diphenyl ether and o,o'-dibromodiphenyl ether precursors is described.Tricyclic oxasilepins are formed from o,o'-dibromobenzylphenyl ether by metallation with n-BuLi followed by reaction with dichlorosilanes as well as by ring expansion of an appropriate phenoxasilin.Reactions at the silicon center and at the ring methylene carbon of the oxasilepins are reported, as well as attempts to generate oxasilocins.

- Bidentate phosphine ligand
-
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.
