Versuchsvorschrift
3-Formyl-2-phenylbicyclo[2,2,2]octa-2,5-diene (3.7 g; 0.018 m) 5% Palladium on charcoal (0.3 g) and ethyl acetate (100 ml) were hydrogenated for 1 week. The catalyst was filtered off and the filtrate evaporated, then the residue distilled twice; Yield 1.9 g (51%) b.p. 160° C. at 0.2 mm/Hg.
