Abstract (en)
[origin: WO2005082830A1] A process for the carbonylation of unsaturated compounds by contacting the unsaturated compound with carbon monoxide in the presence of a catalyst system comprising: (a) a source of palladium and/or platinum; and (e) an unsymmetrical bidentate diphosphine ligand of formula (I), R<1>R<2> > P<1> - R<3> - P<2> < R<4>R<5> (I) wherein P<1> andp P<2 >represent phosphorus atoms; R<3> represents a divalent organic bridging group; and R<1>, R<2>, R<4> and R<5> each individually, or R<l> and R<2> jointly, and/or R<4> and R<5> jointly represent organic groups that are covalently linked to the phosphorus; and wherein R<1>, R<2>, R<4> and R<5> are chosen in such way, that the phosphino group R<1>R<2> > P<1> differs from the phosphino group P<2 >< R<4>R<5>.
