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).
