4-Fluorophenylacetylene Chemical Properties,Usage,Production

  • Chemical Properties White Crystalline Solid
  • Uses 1-Ethynyl-4-fluorobenzene, a substituted phenylacetylene, may be used in the synthesis of aryl acetylenes, via Sonogashira type cross coupling reaction with various haloarenes in the presence of bis(μ-iodo)bis((-)-sparteine)dicopper(I) catalyst.
  • Uses Intermediates of liquid Crystals. As pharmaceutical intermediates. As organic synthesis intermediates. For vacuum deposition.
  • Uses Intermediates of Liquid Crystals
  • Synthesis Reference(s) Synthesis, p. 589, 1996 DOI: 10.1055/s-1996-4265
  • General Description 1-Ethynyl-4-fluorobenzene (pFAB) is a fluorobenzene derivative. Trianionic pincer alkylidyne complex catalyzed polymerization of 1-ethynyl-4-fluorobenzene has been reported. The surface of the iodophenyl-terminated organic monolayers has been modified by Sonogashira coupling of the iodophenyl groups found on the surface with pFAB. Dimerization catalyzed by Y[N(TMS)2]3 and 4-chloroaniline gave exclusive formation of one of three possible enediynes in excellent yield.
