Sažetak

Anodic oxidation of 1-arylmethylenesemicarbazides (1-5) was
performed in methanol-tetraethylammonium perchlorate electrolyte
solution by constant-current electrolysis. As a result of anodic
oxidation, the corresponding oxadizoles (la-3a) were isolated in
good yields, ranging from 51 to 65%. The anodic oxidation represents
a novel efficient conversion of an aromatic aldehyde to an aromatic methyl ester (3b-5b) through oxidation of its semicarbazones.
