coupling of allyl alcohols with nitroalkanes, nitriles, and aldehydes using catalytic Pd(PPh3)4 has been accomplished viaactivation of C–OH bonds with CO2. The in situ formation of carbonates from alcohols and CO2 facilitates oxidativeaddition to Pd to form reactive π-allylpalladium intermediates. In addition, the formation of a strong baseactivates nucleophiles toward the reaction with the π-allylpalladium
