Document Type and Number:
Japanese Patent JP2006528227
Kind Code:
A
Abstract:
A process for the hydrocarboxylation of an ethylenically unsaturated carboxylic acid, by reacting it with carbon monoxide and a co-reactant selected from the group of water and carboxylic acids in the presence of a catalyst system including: (a) a source of palladium; (b) a bidentate diphosphine of formula (I), R1R2>P-R3-R-R4-P5R6 (I) wherein P represents a phosphorus atom; R1, R2, R5 and R6 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; R3 and R4 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 of less than 3, as measured at 18° C. in an aqueous solution.
