Popis:	Wittig-reaction intermediates derives 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 ylieds with aliphatic aldehydes.
