Patent

CA 2059233

The invention relates to a process for the monocarbonylation of optionally substituted olefinically unsaturated compounds by reaction with carbon monoxide and a coreactant in the presence of a catalyst system comprising: a) a source of palladium cations, b) a source of bidentate diphosphine, and c) a source of anions, characterized in that the diphosphine is selected from the group of diphosphines of formula I, R1R2P-X-PR3R4 (I) wherein R1, R2, R3 and R4 independently represent an optionally substituted aliphatic group, or R1 and R2 together and/or R3 and R4 together represent an optionally substituted bivalent aliphatic group, and X represents a bivalent bridging group containing from 1 to 10 atoms in the bridge, to produce various carbonyl compounds including aldehydes, ketones, esters, and amides. The invention also relates to certain catalyst systems useful in this reaction.
