Title:
Process for the carbonylation of ethylenically unsaturated compounds
Document Type and Number:
WIPO Patent Application WO2001068583
Kind Code:
A3
Abstract:
Process for the carbonylation of ethylenically unsaturated compounds having 3 or more carbon atoms by reaction with carbon monoxide and an hydroxyl group containing compound in the presence of a catalyst system. The catalyst system includes(a) a source of palladium cations;(b) a bidentate diphosphine of formula I,wherein P represents a phosphorus atom; R<1>, R<2>, R<5 >and R<6 >independently represent the same or different optionally substituted organic groups containing a tertiary carbon atom through which the group is linked to the phosphorus atom; R<3 >and R<4 >independently represent optionally substituted alkylene groups and R represents an optionally substituted aromatic group;(c) a source of anions derived from an acid having a pKa less than 3, as measured at 18° C. in an aqueous solution. The process is carried out in the presence of an aprotic solvent.
