Abstract
Structural studies by X-ray analysis and NMR spectroscopy of the pi-al lyl complex, [Pd(eta(3)-1,3-diphenylallyl)((S)-BINAP)]-PF6 . AcOEt, ha ve been carried out, and revealed the stereochemical feature for the i ntermediate of palladium-catalyzed asymmetric allylic alkylation. The dissimilarity of the two phenyl groups attached to the pi-allyl moiety is assumed to be one of the origin of the selectivity. In solution tw o configurational isomers, (syn, syn) and (syn, anti), exist.
