        Camphene is found to undergo the Oxo reaction smoothly when diluted with an equal volume of benzene using dicobalt octacarbonyl as catalyst.  It gives liquid aldehyde of constant boiling point in 65% yield.  It undergoes the Oxo reaction without rearrangement giving an aldehyde which is structurally related to isocamphenilanaldehyde by several methods of degradation.  Oxidation of the aldehyde with air or O₂ gives a simple acid m. p. 56°-57° of the same chain length.
