Abstract

Alkyl pentenoates are prepared by reacting butadiene with carbon monoxide and an alkanol in the presence of a cobalt carbonyl complex and a tertiary, aromatic heterocyclic nitrogen base at from 80.degree. to 160.degree. C. under from 100 to 1,000 bar in the presence of from 0.1 to 10% by volume of hydrogen, based on the amount of carbon monoxide used.
