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 ( and ′). The products
