2-Butynoic acid Chemical Properties,Usage,Production

  • Chemical Properties white to yellow powder
  • Uses Synthon employed in a variety of reactions, including cycloacylation of phenols to flavones and chromones,1 and cyclization to γ-butyrolactones.2
  • Uses 2-Butynoic acid is used as an intermediate in organic synthesis and pharmaceuticals. It is used as a synthon in various reactions, which includes cylcoalkylation of phenols to flavones and chromones. It is involved in the cyclization of gamma-butyrolactones. It is also used in the synthesis of Z-trisubstituted olefins through μ-alkylation. It plays an important role in the preparation of chirally pure 1,2,3,4-tetrahydroisoquinoline analogs, which finds application as anti-cancer agents.
  • General Description The rotational spectrum of 2-butynoic acid was measured by pulsed supersonic-jet Fourier transform microwave spectroscopy.
