As ligands, these compounds can act as either two- or four-electron donors.
One of these functional groups lies adjacent to a quaternary carbon in the antifungal terbinafine. As ligands, these compounds can act as either two- or four-electron donors. In the presence of nickel catalysts these compounds can trimerize into arenes. When they're hydroxylated they instantly transform into carbonyls by tautomerization. Two equivalents of hydrogen bromide can be used to transform them into (*) geminal halides. Reacting these compounds with sodium metal dissolved in liquid ammonia gives the trans-alkene product, and they can be transformed into cis-alkenes via Lindlar's catalyst. These compounds contain two sp-hybridized carbons linked by one sigma and two pi bonds. For 10 points, name this functional group that contains a carbon-carbon triple bond.
