ABSTRACT:
A method for the preparation of organic esters of oxalic acid by reaction of carbon monoxide under pressure with the corresponding alcohol is disclosed, the improvement consisting in the use of a quite particular catalyst system. The catalyst is a binary system in which the principal member is a palladium complex and the co-catalyst is a compound, preferably an organic compound having an acidic nature, no matter how weak.
