The present invention concerns a process of carbonylation of poly-unsaturated diene with high selectivity for the preparation of a β,γ- unsaturated carboxylic acid or ester in the presence of water or alcohol and catalyzed by [PdCl2P2] complex wherein P2 is two mono or one bidendate phosphine ligand.
本发明涉及一种在
水或醇的存在下,由[PdCl2P2]复合物催化的,具有高选择性的聚不饱和二烯的羰基化过程,用于制备β,γ-不饱和
羧酸或酯。其中P2是两个单
磷或一个双齿
膦配体。
