Versuchsvorschrift
This alkyne was dissolved in 30 ml of ethy acetate and hydrogenated over 2 g of Pd/C (10%) at room temperature and under 1 atm H2. Filtration over diatomaceous earth and removal of the solvent gave 3.08 g of 2-hexyl-9,9-dimethyl-6,7,8,9-tetrahydro-5H-benzocycloheptene as a colorless oil (GC purity: 98%).
