Electrosyntheses based on reactions of addition of electrochemically generated radicals to ethylene and its derivatives—I. Electrosynthesis products and the influence of electrolysis conditions on the addition product yield

Abstract

It is shown that radicals electrochemically generated under Kolbe and Brown—Walker syntheses can, in principle, be added to ethylene and is derivatives. Products formed under electrolysis of acetic, monochloroacetic, trichloroacetic, trifluoroacetic, propionic, oxalic and other acids, as well as monomethylglutarate and monomethyladipinate, in the presence of various acceptors, such as ethylene, propylene, fluoroolefins and dimethyl ester of maleic acid, are separated and identified. It is shown that products of type ▪ The influence of electrolysis conditions on the addition product yield is investigated. An increase in the acceptor concentration is shown to increase the total yield of addition products and the yield of higher oligomers. An increase in the current density reduces the yield of addition products.
