For 10 points, name this class of compounds that feature a linear, carbon-carbon triple bond.
Molecules with this functionality can react with carbonyls in the Conia- Ene reaction in the presence of a gold catalyst. Two equivalents of their terminal variety can be joined in the Eglinton reaction or Cadiot-Chodkiewicz coupling, and vinyl and aryl halides can join to them in Sonogashira coupling. They can form cyclopentenones with alkenes and carbon monoxide in the Pauson- Khand reaction, and butyllithium and triphenylphosphine can be used to create them in the Corey-Fuchs reaction. A palladium catalyst doped with quinoline can be used to reduce them to alkenes, and that catalyst is named after Lindlar.
