Product Description
Ethyltriphenylphosphonium bromide, often abbreviated as EtPh3P+Br-, is a quaternary ammonium salt commonly used in organic chemistry as a Wittig reagent. It is derived from the reaction between triphenylphosphine and ethyl bromide. Ethyl Triphenyl Phosphonium Bromide is particularly useful in the Wittig reaction, a method for the synthesis of alkenes from aldehydes or ketones. In this reaction, the phosphonium salt reacts with a strong base to generate a phosphorane ylide, which then undergoes a Wittig olefination with the carbonyl compound to form the desired alkene product. The ethyl group in the molecule serves as a handle for subsequent manipulations or reactions.
