Initial Interaction of Triphenylphosphonium-2-propenylide with Prenal Prior to Wittig Olefination
摘要:
The interaction of triphenylphosphonium-2-propenylide (2) with prenal (6) is shown to proceed via initial C-gamma-C-1 addition, followed by dissociation of the coupling product and C-alpha-C-1 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.
