Abstract
Conclusions1.Electrochemical oxidation of esters of ethane-1,1,2,2-tetracarboxylic acid in the presence of hydrohalic acid salts in acetonitrile leads to esters of ethylenetetracarboxylic acid; in alcohols not only an oxidative dehydrogenation takes place, but also esters of 1-alkoxyethane-1,1,2,2-tetracarboxylic acid are formed.2.When the reaction is carried out in methanol, the yield of the ester of ethylenetetracarboxylic acid and the ester of 1-methoxyethane-1,1,2,2-tetracarboxylic acid depends on the temperature, type of carrier-catalyst, and under the optimal conditions, each of the esters can be obtained in a yield of up to 80%.3.A mechanism has been proposed for the electrochemical oxidation of esters of ethane-1,1,2,2-tetracarboxylic acid, including the formation of the α-anion of the ester on a cathode, generation of a molecular halogen on the anode and their chemical transformations in solutions.
