One of these molecules, an alkene, and carbon monoxide react to form a cyclopentenone in the Pauson-Khand reaction. Only terminal, not internal, examples of these molecules display C-H stretches in IR spectroscopy. Hydroboration or oxymercuration of these molecules results in an enol that tautomerizes to an aldehyde or keto
One of these molecules, an alkene, and carbon monoxide react to form a cyclopentenone in the Pauson-Khand reaction. Only terminal, not internal, examples of these molecules display C-H stretches in IR spectroscopy. Hydroboration or oxymercuration of these molecules results in an enol that tautomerizes to an aldehyde or ketone. The cyclization of these molecules with an azide is a widely-applied click reaction. Terminal forms of these molecules have a pKa of 25. Lindlar's catalyst can reduce them to cis-alkenes. The simplest example of this class of molecule is acetylene, or ethyne. For 10 points, name this class of molecules containing a carbon-carbon triple bond.
