| | Allylidenetriphenylphosphorane Usage And Synthesis |
| Uses | Allylidenetriphenylphosphorane is used as a wittig reagent for 1,3-diene synthesis and Michael addition reaction. | | Preparation | 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. | | storage | Allylidenetriphenylphosphorane must be prepared and transferred under inert gas (Ar or N2) to
exclude oxygen and moisture. |
