EATON'S REAGENT Usage And Synthesis
Chemical PropertiesClear colorless to light yellow liquid
UsesEaton′s Reagent may be used in the synthesis of the following:
  • Fluorene-based hole-transporting material.
  • Mono and bis-chalcone derivatives via Claisen-Schmidt condensation reaction between arylaldehydes and ketones.
  • 4-Hydroxycoumarins and 4-hydroxy-2-quinolinones derivatives.
UsesEaton's Reagent is used in the synthesis fluorine-based hole-transporting material, mono and bis-chalcone derivatives via Claisen-Schmidt condensation reaction between arylaldehydes and ketones and 4-hydroxycoumarins and 4-hydroxy-2-quinolinones derivatives.
General DescriptionEaton′s Reagent contains 7.7wt% phosphorus pentoxide in methanesulfonic acid. It is commonly used as a catalyst and condensing agent.
