The interaction of triphenylphosphonium-2-propenylide (2) with prenal (6) is shown to proceed via initial C(γ)-C1 addition, followed by dissociation of the coupling product and C(α)-C1 recombination to produce the corresponding betaine, which eliminates triphenyphosphine oxide to yield (E)- and (Z)-6-methyl-1,3,5-triene (7a,b) as the Wittig olefination products.
