General description
2-Ethynylpyridine is a pyridine derivative.
Application
2-Ethynylpyridine has been used to synthesize:
- poly(2-ethynyl-N-iodopyridinium iodide), via in-situ uncatalyzed polymerization
- poly[2-ethynyl-N-(2-furoyl)pyridinium chloride
- poly[2-ethynyl-N-(propylsulfonate)pyridinium betaine]
- 4-(2′-pyridyl)-1,2,3-triphospholide anion, via reaction with anionic heptaphosphide clusters
- poly[N-(carboxymethyl)-2-ethynylpyridinium bromide], a new water-soluble ionic conjugated polymer
- self-doped ionic conjugated polymer, poly(2-ethynylpyridinimum N-benzoylsulfonate).
Other Notes
