Reaktionsschritte

50 g of dihydrocarvone, 1.5 g of triphenylphosphene and 0.013 g of rhodium 2-ethylhexanoate are reacted as described in Example 1 in 200 ml of toluene at 150° C. and under 280 bar with a 1:1 mixture of hydrogen and carbon monoxide. The distillative working-up yields 51.5 g of 3-(4-methyl-3-oxocyclohexyl)-butyraldehyde (boiling point=98°-100° C./0.1 mbar, 86% of theory).
