摘要: By anodic decarboxylation carboxylic acids can be converted simply and in large variety into radicals. The combination of these radicals to form symmetrical dimers or unsymmetrical coupling products is termed Kolbe electrolysis (Scheme 1, path a). also added double bonds afford additive monomers dimers, an intramolecular version lead five-membered heterocycles carbocycles b). intermediate radical further oxidized a carbenium ion c). This oxidation favored by electron-donating substituents at the α-carbon acid, basic electrolyte, graphite as anode material salt additives, e.g. sodium perchlorate. carbocations that are formed solvolysis, elimination, fragmentation rearrangement. pathway frequently called nonKolbe electrolysis.
