Abstract
The anodic decarboxylation of 3-oxanonanoic acid (2a) and 3-oxapentade canoic acid (2b) in methanol leads exclusively to products of the non- Kolbe electrolysis. The influence of coelectrolysis, solvent, current density, degree of neutralization and chain length of the alkoxy group on the anodic decarboxylation of 2a, b have been investigated. An ext ended alkyl chain in the alkoxy group, coelectrolysis with long-chain fatty acids, ethanol or dimethylformamide as solvent, and a high curre nt density favor the Kolbe coupling against the non-Kolbe electrolysis .
