실험 절차

Lithium wire, 0.75 g, was dissolved in 300 mL of ammonia at -78° C. A solution of 10.1 g of 11,11-diphenyl-11-methoxyundec-1-ene in 20 mL of THF to the lithium solution and the mixture was stirred at reflux for 30 min. To a reaction vessel were added sequentially 5 mL isoprene, 5 mL of methanol, and 10 g of ammonium chloride and the ammonia allowed to evaporate at room temperature. Diethyl ether was added to the mixture and the solution was washed with water and brine (saturated aqueous sodium chloride). The organic layer was dried and concentrated in vacuo to give 9.7 g of 11,11-diphenylundec-1-ene which is characterized by:
