Abstract
A general characteristic of processes that occur during anodic oxidn. of phenylacetic and phenylpropionic acids and derivs. of a- and b-amino acids on platinum electrodes in methanol and mixed pyridine-methanol solns. is given. From preparative electrolyzes in stagnant and flow-through reactors, conditions are detd. under which the dimerization (Kolbe electrosynthesis) is least complicated by the formation of polymer products. Properties of removed electrodes, on which stable polymer films formed during the electrosynthesis, are examd. For films formed in certain conditions on the cathode, the presence of a quasi-reversible redox transition is demonstrated. Such films contain disperse platinum codeposited with polymer as a result of the anode dissoln. in the cells with common compartments. In principle, the film-modified electrodes can be used for controlling anodic decarboxylation.

Abstract
The electrochem. oxidn. of aliph. carboxylic acids, hexanoic, heptanoic, and lauric acid, under biphasic conditions was studied as a model system for ultrasound enhanced Kolbe electrosynthesis processes. Power ultrasound was used to generate an in situ emulsified medium and to remove reaction products continuously from the electrode surface. A clean and highly efficient process at platinum electrodes with formation of 'one electron' products only occurs in marked contrast to processes in monophasic media. For hexanoic acid the Kolbe dimer product R-R is formed in up to 75% yield with 45% current efficiency at 0.18 A cm-2 c.d. and in the presence of 190 W cm-2 ultrasound. The mechanism is explained in terms of a dynamically modified electrode surface, at which hydrophobic products are immediately 'trapped' via partitioning into a nonpolar org. phase and transported away into the emulsion system. Kolbe electrosynthesis is undertaken both at platinum electrodes and at free-standing polycryst. boron-doped diamond electrodes, to minimize the surface erosion effect induced by power ultrasound. The type and yield of products obtained from the biphasic Kolbe electrolysis process at diamond electrodes are essentially identical to those obsd. at platinum and based on this observation, the presence of a biphasic reaction layer at the electrode surface is postulated to govern the process.
