Chemische Eigenschaften
white crystalline powder
Verwenden
Allyltriphenylphosphonium bromide is used for the first time in the preparation of DES. It has been shown to be part of Phosphonium salts, having antiviral activity against influenza virus A. It can be used in witting olefination of aldehydes for preparation of conjugated dienes.
synthetische
Allyltriphenylphosphonium bromide was synthesized from the reaction of triphenylphosphine and allyl bromide in dry toluene.
Application
