In the presence of a strong base, this functionality is changed from internal to external in a namesake zipper reaction.
In the presence of a strong base, this functionality is changed from internal to external in a namesake zipper reaction. Substituted forms of this functional group can be created from aryl ketones in the Seyferth-Gilbert homologation. 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. For 10 points, identify this functional group, the simplest of which is acetylene, characterized by a carbon-carbon triple bond.
