A polymer-supported Wittig reagent [polystyrene-supported (11-hydroxyundecyl)triphenylphosphonium bromide] was deprotonated to give the polymeric phosphorane, which reacted with EtCHO in THF to give 84% of a mixt of (Z)- and (E)-EtCH:CH(CH2)10OH in a 93:7 ratio. The ratio was determine by gas chromatog. of the acetates, the title sex pheromone.
