PRODUCTION OF BUTANE TETRACARBOXYLIC ACID DERIVATIVES BY MEANS OF COUPLED ELECTROSYNTHESIS

摘要

The invention relates to a method for producing butane tetracarboxylic acid derivatives as a product of value I by coupled electrosynthesis. A compound from the group comprising the maleic acid esters, maleic acid ester derivatives, fumaric acid esters or fumaric acid ester derivatives is selected. At least one hydrogen atom in positions 2 and 3 is substituted by inert groups, is cathodically reduced and a product of value II is obtained on the anode.
