PRODUCTION OF BUTANE TETRACARBOXYLIC ACID DERIVATIVES BY MEANS OF COUPLED ELECTROSYNTHESIS

PRODUCTION OF BUTANE TETRACARBOXYLIC ACID DERIVATIVES BY MEANS OF COUPLED ELECTROSYNTHESIS

A process for preparing butanetetracarboxylic acid derivatives as product of value I by coupled electrosynthesis which comprises cathodically reducing a compound selected from the group consisting of maleic esters, maleic ester derivatives, fumaric esters and fumaric ester derivatives where at least...

Zusammenfassung:A process for preparing butanetetracarboxylic acid derivatives as product of value I by coupled electrosynthesis which comprises cathodically reducing a compound selected from the group consisting of maleic esters, maleic ester derivatives, fumaric esters and fumaric ester derivatives where at least one hydrogen atom in positions 2 and 3 may be replaced by inert groups and obtaining a product of value II at the node.
