Rh-catalyzed allylic substitutions are believed to exhibit a "memory effect" causing the nucleophile to predominately attack at the position of the leaving group . Therefore, Rhcatalyzed branched selective allylic arylations are dominated by using branched allylic (pseudo)halide substrates , and very few examples of Rh-catalyzed asymmetric allylic substitution of prochiral allylic electrophiles with achiral nucleophile are known none of which use non-stabilized (pKa > 25) nucleophiles.
