      This functional group can be created from aldehydes in the Corey-Fuchs reaction. In the presence of palladium deposited on calcium carbonate and (*) poisoned with lead, a compound known as Lindlar’s catalyst, this functional group can be hydrogenated to an alkene.

      Following Corey and Fuchs,86 (2,2-dibromoethenyl)cyclohexane87 (1.22 g, 4.5 mmol) in THF (20 cm3) was cooled to –78 °C under argon, and n-butyllithium (2.3 mol dm–3 solution in hexane, 4.2 cm3, 9.5 mmol) added. The mixture was stirred at –78 °C for 1 h, then gradually warmed to room temperature and kept at this temperature for 1 h.
