N2 - Structural studies by X-ray analysis and NMR spectroscopy of the π-allyl complex, [Pd(η3-1,3-diphenylallyl)((S)-BINAP)]PF6·AcOEt, have been carried out, and revealed the stereochemical feature for the intermediate of palladium-catalyzed asymmetric allylic alkylation. The dissimilarity of the two phenyl groups attached to the π-allyl moiety is assumed to be one of the origin of the selectivity. In solution two configurational isomers, (syn, syn) and (syn, anti), exist.
