C(sp³)–O Bond-Forming Reductive Elimination of Ethers from Bisphosphine-Ligated Benzylpalladium(II) Aryloxide Complexes

On the contrary: Isolated benzylpalladium aryloxide complexes undergo C(sp³)O bond-forming reductive elimination by a stepwise ionic mechanism (see scheme) distinct from the accepted concerted pathway for reductive elimination of aromatic ethers from arylpalladium(II) species. The mechanism is proposed to result from dissociation of the aryloxide ligand followed by nucleophilic attack on the benzylic carbon atom. Read more on publisher's site.
