A high regioselectivity has been observed in the palladium catalyzed allylation of “soft” nucleophiles (pentane-2,4-dione and 4-hydroxy-6-methyl-2-pyrone) when both allylic termini have the same steric requirements and different electronic features.

Nucleophilicattacks on π-allylpalladiumcomplexes derived from O2NPh(CHCHCH)PhX systems (X = 4-OMe and 4-Cl) occur prefentially at the allylic terminus remote from the electron-withdrawing group (NO2).
