Carbonylation of conjugated dienes.

摘要

The invention relates to a process for the preparation of an alkenoic acid derivative by reaction of an aliphatic conjugated diene with carbon monoxide and a hydroxyl group-containing compound in the liquid state in the presence of a catalyst system comprising a palladium compound, a multidentate phosphine ligand, and optionally a protonic acid, wherein the reaction is conducted in a reaction medium of controlled polarity.
