Ethyltriphenylphosphonium Bromide (ETPB) is a phase-transfer catalyst that accelerates the curing of phenolic-based epoxy resins, certain fluoroelastomer resins, and thermosetting powder coatings. It also serves as a catalyst in the synthesis of various organic compounds and functions as a pharmaceutical intermediate.
ETPB is utilized as a reactant in the synthesis of D-amino acids from L-cysteine-derived thiazolidines, Leiodolide A via aldol reactions, and in Horner–Wadsworth–Emmons olefination.
Additionally, it is applied in the preparation of cycloalkanoindolines through diastereoselective intramolecular inimo-ene reactions.
It is also employed as a reagent in solid-state metathesis polycondensation for producing alkyl-dipropenylthiophene monomers, as well as in Mizoroki–Heck cyclization and cascading Tsuji–Trost cyclization reactions.
