[EX Q]: One reaction to prepare these compounds adds diazomethylphosphonate esters to aldehydes under basic catalysis and generates vinyl-diazo intermediates. Along with aldehydes, these compounds are the degradation products of alpha, beta-epoxy tosylhydrazones in the Eschenmoser fragmentation. A coupling involving both palladium and copper catalysis, in which these compounds react with aryl halides, is the Sonogashira reaction. These compounds react with azides to form triazole rings in a well-known click-chemistry reaction, and terminal ones can be deprotonated by sodium amide. They are reduced to cis-alkenes by the poisoned Lindlar catalyst. This functional group is composed of two sp-hybridized carbons. For 10 points, name this functional group consisting of a carbon-carbon triple bond.
