A new method for α,α-diallylation of ketones catalyzed by palladium-phosphine complexes under neutral conditions has been developed. Allylation of β-keto carboxylates with allylic carbonates, followed by the decarboxylation-allylation as a one-pot reaction affords diallylated ketones in good yields.
