Document Type and Number:
Japanese Patent JP2002540091
Kind Code:
A
Abstract:
The present invention relates to a process for the carbonylation of conjugated dienes, whereby a conjugated diene is reacted with carbon monoxide and a hydroxyl group containing compound in the presence of a catalyst system including: (a) a source of palladium cations, (b) a phosphorus-containing ligand, (c) a source of anions, wherein the phosphorus-containing ligand is a ligand having the general formula (I): X<1>-R-X<2 >wherein X<1 >and X<2 >represent a substituted or non-substituted cyclic group with at least 5 ring atoms, of which one is a phosphorus atom, and R represents a bivalent organic bridging group, connecting both phosphorus atoms, containing from 1 to 4 atoms in the bridge, whereby the carbonylation process can be performed batch wise, semi-continuously or continuously.
