smoothly with CO (1 atm) and n-butanol in the presence of a tertiary amine and a catalytic amount of bis(triphenylphosphine)palladiumdichloride to afford the corresponding esters. When ethanol and a disubstituted substrate are used under milder conditions, selective mono-carboalkoxylation occurs. Amidation is effected using a primaryamine as nucleophile.
