PROBLEM TO BE SOLVED: To provide an industrial method for producing aβ-hydroxy ester, and to provide an industrial method for producing a dicobalt octacarbonyl complex-containing substance used for theβ-hydroxy ester. SOLUTION: This method for producing theβ-hydroxy ester is characterized by reacting an epoxide with an alcohol and carbon monoxide in the presence of a cobalt carbonyl compound as a catalyst and an azole compound in a cocatalyst in an organic solvent. This method for producing the dicobalt octacarbonyl complex-containing substance is characterized by reacting a cobalt compound with a mixture gas of carbon monoxide with hydrogen in the presence of a metal such as Pd, Rh, Pt or Ru as a catalyst in an organic solvent.
