New insight into Pd‐catalyzed allylic substitution : A cationic π‐allylpalladium( II ) complex is generated by the oxidative addition of allylic acetate to the palladium( 0 ) complex generated from a mixture of Pd(dba) 2 +2 PPh 3 . This reaction is reversible and proceeds through at least two successive equilibria to afford free ions in DMF and ion pairs in THF (see diagram).
