Chapter 24, Problem 24.21P

Interpretation Introduction

Interpretation:

${\eta }^3$-allylic complex created in the catalytic cyclic of the given reactant with $Pd{L}_4$ and chirality in ligand L that would influence the stereochemistry of the nucleophilic attack has to be described.

Concept Introduction:

In catalytic allylic alkylation, a nucleophile, enolate of a doubly activated $\text{α-}$ carbon replaces an allylic leaving group, such as acetate. The reaction occurs in presence of $Pd$ as the catalyst.

Stereochemistry at the alkylation carbon is retained.
