ABSTRACT:
A process for the preparation of oxalate esters by reacting carbon monoxide with an alcohol in the presence of a stoichiometric quantity of a metal salt catalyst and a stoichiometric quantity of an amine base. Preferably stoichiometric amounts of particular metal oxidizing salts are employed along with the metal salt catalyst and a stoichiometric amount of amine base. Alternatively ligands of the metal salt catalysts may be employed, especially in conjunction with a metal oxidant and an amine base thereby providing a pronounced effect on selectivity for the oxalate ester over the carbonate.
