5-Cyanovaleric acid and its esters are manufactured by reacting pentenonitriles with water or alcohols and carbon monoxide in the presence of metal carbonyls and heterocyclic compounds at elevated temperature under pressure. 5-Cyanovaleric acid and its esters are starting materials for the manufacture of dyes, pesticides, fibers, especially nylon fibers, and plastics.
