용도

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. It is also used in the preparation of cycloalkanoindolines through diastereoselective intramolecular inimo-ene reactions. Further, it is used as a reagent in solid-state metathesis polycondensation to prepare alkyl-dipropenylthiophene monomers and Mizoroki-Heck cyclization and cascading Tsuji-Trost cyclization reactions.

참고

Hygroscopic. Incompatible with oxidizing agents.

Reaction of the phosphorane (generated using 1 mole of n-BuLi) with an aldehyde at low temperature, followed by a second mole of n-BuLi, gives the -oxido phosphonium ylide which can then be reacted with 1,2-diiodoethane to give (Z)-2-iodo-2-alkenes with high stereoselectivity: J. Chem. Soc., Perkin 1, 1331 (1995). See Appendix 1.
