Process for the preparation of alkyl pentenoates by reacting butadiene with carbon monoxide and alkanols in the presence of cobalt carbonyl complexes and tertiary, aromatic heterocyclic nitrogen bases at a temperature of 80 to 160 ° C and under a pressure of 100 to 1000 bar, characterized in that 0.1 up to 10 mol% of water, based on the butadiene used. |
