A series of π-allylpalladiumcomplexes with neutral monodentate and bidentate ligands were prepared and examined for their ability to undergo stoichiometric umpolung allylation reactions with benzaldehyde. Neutral bidentate N-heterocyclic carbene ligands promote nucleophilicattack. Catalytic allylation reactions of aromatic and aliphatic aldehydes are reported.
