Reversibility of a Wittig Intermediate derived from a Triphenylphosphonium Ylide and an Aliphatic Aldehyde

Wittig-reaction intermediates derived from hexanal and (γ-oxidopropylidene)triphenylphosphorane, (1), are freely reversible, as indicated by significant quantities of cross-over products from a second aldehyde (octanal); such a result may account for anomalously enhanced E stereoselectivity in the reaction of γ- and β-oxido ylides with aliphatic aldehydes.
