Versuchsvorschrift

To a Parr hydrogenation bottle was added 4,4-diphenyl-2-cyclohexen-1-one (0.91 g, 3.66), dissolved in methanol (20 mL), followed by the addition of 10% Pd/C (0.2 g). This mixture was hydrogenated at 50 psi overnight. After the catalyst was filtered and washed with methanol, the filtrate was concentrated in vacuo to give 0.90 g of 4,4-diphenyl-cyclohexanone. MS (EI) calcd: M+H=251.1; found: 251.1.
