Wittig reagent for the two-carbon homologation of aldehydes to ,-unsaturated esters. Also used in an efficient synthesis of pyrazoles via reaction with methyl diazoacetate in the presence of triethylamine.
Methyl 2-(triphenylphosphoranylidene)acetate serves as a stable, bench-ready phosphorus ylide reagent enabling reliable Wittig reactions. It facilitates efficient olefination of aldehydes and ketones under mild conditions, offering high stereoselectivity for (Z)-alkenes in standard synthetic workflows. Its compatibility with diverse functional groups and ease of purification make it a practical choice for constructing conjugated systems and complex molecular architectures in organic synthesis.
