Abstract
Abstract Pyridine and oligopyridines bearing halide or triflate groups react smoothly with CO (1 atm) and n -butanol in the presence of a tertiary amine and a catalytic amount of bis(triphenylphosphine)palladium dichloride 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 primary amine as nucleophile.
