Carbon monoxide is oxidatively coupled by ligand nickel(II) compounds with secondary, primary amines and with alkali alkoxides to give oxalic acid derivatives. In the case of secondary amines the CO coupling can be run catalytically by adding oxidants like copper(II) salts. The yield of oxalic esters depends on the types of ligands and anions.
