Allylidenetriphenylphosphorane Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Allylidenetriphenylphosphorane is used as a wittig reagent for 1,3-diene synthesis and Michael addition reaction.
synthetische
Allylidenetriphenylphosphorane is generally prepared from Allyltriphenylphosphonium Bromide
or chloride by treatment with n-Butyllithium or Phenyllithium. Structurally related analogs have been
prepared by the similar methods: 2-butenylidenetriphenylphosphorane; 3-methyl-2-
butenylidenetriphenylphosphorane; (E)-2-octenylidenetriphenylphosphorane; (E)-
pentadienylidenetriphenylphosphorane; (E)-2,4-hexadienylidenetriphenylphosphorane; 2-
alkynylidenetriphenylphosphorane; allylidenetributylphosphorane. γ-Alkyl-substituted
allylidenetriphenylphosphorane can be also obtained by the reaction of diisobutylaluminum
alkylideneamide with methylidenetriphenylphosphorane.
