Vinyltriphenylphosphonium bromide Usage And Synthesis
UsesTriphenylvinylphosphonium Bromide has been used to enhance the thermal stability of epoxy resin. It is commonly used as a Wittig reagent.
Chemical PropertiesWHITE TO BEIGE FINE CRYSTALLINE POWDER
UsesReactant involved in:
  • Asymmetric conjugate addition and intramolecular cyclization
  • Condensation with benzoxazinediones
  • Intramolecular dehydrobromination
  • Schweizer reaction
  • Cycloaddition with nitro ketone Baylis-Hillman adducts
', 'Reagent for the synthesis of heterocycles.
PreparationThe preparation of TriphenylvinylphosphoniuM BroMide has been accomplished by treatment of ethylenebis(triphenylphosphonium) dibromide with borate ion (32%), (2-chloroethyl)triphenylphosphonium bromide with Triethylamine (72%), (2-bromoethyl)triphenylphosphonium bromide with Silver(I) Oxide (85%), and (2- phenoxyethyl)triphenylphosphonium bromide with boiling ethyl acetate (92%).
reaction suitabilityreaction type: C-C Bond Formation
storagehygroscopic; irritant; produces sneezing in many individuals. Use in a fume hood.
