Abstract
Preparation of dialkyl oxalates by the oxidative carbonylation of alcohols which comprises reacting carbon monoxide with an alcohol in the presence of a catalytic amount of a catalyst comprising palladium in complex combination with a ligand and in the presence of a stoichiometric amount of a quinone. Advantageously, carboxylic acid cocatalysts may be employed in addition to the palladium-containing catalyst.
