Palladium-Catalyzed Decarboxylation-Carbonylation of Allylic Carbonates To Form β,γ-Unsaturated Esters
Allyl alkyl carbonates undergo a smooth decarboxylation-carbonylation reaction to afford β,γ-unsaturated esters at 50 deg C under atmospheric or low pressure of carbon monoxide and neutral conditions in the presence of palladium-phosphine complexes as catalysts.The reaction offers a very good method for the preparation of β,γ-unsaturated esters from allylic alcohols.
