| titleOfInvention | Method for carbonylating ethylenically unsaturated compounds, bidentate diphosphine composition used in the method, and method for preparing the bidentate diphosphine composition |
| abstract | A process for carbonylating an optionally substituted ethylenically unsaturated compound with carbon monoxide and a co-reactant in the presence of a catalyst system. The catalyst system includes (a) a source of a Pt group metal cation and (b) a bidentate diphosphine composition. More than 60% by weight of the bidentate diphosphine present in the bidentate diphosphine composition is represented by the general formula (II), X 1 -R-X 2 , wherein X 1 and X 2 are independently at least 5 Represents an optionally substituted symmetric phosphabicycloalkyl group having the following ring atoms, and both R represent a divalent organic bridging group attached to the phosphorus atom. More than 60% by weight of the bidentate diphosphines present are of the general formula (II), X 1 -R-X 2 , wherein X 1 and X 2 independently have at least 5 ring atoms, optionally Represents a substituted symmetric phosphabicycloalkyl group wherein R represents a divalent organic bridging group that is bonded to a phosphorus atom, wherein the bidentate diphosphine is 1,3-PP'bis (9-phospho). A bidentate diphosphine composition that is not a Fabicyclo [3.3.1] nonyl) propane. Further, methods for preparing such bidentate diphosphine compositions are described. |
