Abstract

Electrochemical oxidation of catechols to corresponding o‐quinones was successfully performed in aqueous solution by electrolysis at the controlled potentials. Quinones derived from catechols, participate in Michael addition reactions with 5‐phenyl‐1,3,4‐oxadiazole‐2‐thiol and via EC mechanism, converted to corresponding 5‐phenyl‐1,3,4‐oxadiazol‐2‐ylthio‐benzene‐1,2‐diol derivatives (4 and 4′). The products have been characterized using IR, ^1^H NMR, ^13^C NMR, X‐ray, and mass spectral data. J. Heterocyclic Chem., 46, 443 (2009).
