An olefinic hydrocarbon, such aas cyclohexene, is reacted under super atmospheric pressure and at a temperature of at least 100° C. with a mixture of CO and H₂ in the presence of a group II metal having an atomic number of 12-30. such as Ca or Zn. Oxo-carbonyl compounds such as hexahydrobenzaldehyde are obtained. 2 United States patents cited.
