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): X1—R—X2 wherein X1 and X2 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.
本发明涉及一种共轭二烯的羰基化过程,其中在催化剂体系的存在下,将共轭二烯与一氧化碳和含有羟基的化合物反应,所述催化剂体系包括:(a)钯阳离子的来源,(b)含磷配体,(c)阴离子的来源,其中所述含磷配体是具有以下通式(I)的配体:X1—R—X2,其中X1和X2代表至少有5个环原子的取代或非取代环状基团,其中一个是磷原子,R代表连接两个磷原子的双价有机桥接基团,在桥上含有1到4个原子,因此该羰基化过程可以进行批处理、半连续或连续进行。
