title: Disubstituted Z-allylic esters by Wittig-Schlosser reaction using methylenetriphenylphosphorane.
abstract: β-Lithiooxyphosphonium ylides, generated in situ from aldehydes and methylenetriphenylphosphorane, react with halomethyl esters to form disubstituted allylic esters in good yields and with high Z-selectivity.
