Chemical Properties

White to off-white crystalline powder


suzuki reaction


PTC catalyst 


Ethyltriphenylphosphonium Bromide is used as a wittig reagent. Ethyltriphenylphosphonium Bromide and other phosphonium salts show antiviral activity.


Ethyltriphenylphosphonium Bromide (ETPB) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.
  1. Ethyltriphenylphosphonium bromide acts as a reactant in the synthesis of D-amino acids from L-cysteine-derived thiazolidines, Leiodolide A through aldol reactions and Horner-Wadsworth-Emmons olefination.
  2. It is also used in the preparation of cycloalkanoindolines through diastereoselective intramolecular inimo-ene reactions.
  3. it is used as a reagent in solid-state metathesis polycondensation to prepare alkyl-dipropenylthiophene monomers.
  4. Mizoroki-Heck cyclization and cascading Tsuji-Trost cyclization reactions.

Purification Methods

Recrystallise it from H2O and dry it in high vacuum at 100o. IR has bands at 1449, 1431 and 997cm-1 . [Wittig & Wittenberg Justus Liebigs Ann Chem 606 1 1957, Bergmann & Dusza J Org Chem 23 1245 1958, Beilstein 16 IV 982.]
