Versuchsvorschrift

Besides, 30 g of the above-obtained 4-benzyl-2-cyclohexen-1-one were hydrogenated at room temperature for 6 hours using 5 g of Raney nickel in methanol under hydrogen pressure (3 kg/cm2) until the absorption of hydrogen was stopped. After an organic layer was collected by decantation and concentrated, the residue was purified by column chromatography, thereby obtaining 13 g of cis-4-benzylcyclo-hexanol and 14 g of trans-4-benzylcyclohexanol (yield: 90% in total).
