The electroorganic synthesis of 2-amino-5-substituted-1,3,4-oxadiazoles from semicarbazone has been carried out at platinum electrode. This is an environmentally benign electroorganic reaction done under controlled potential electrolysis in an undivided cell. The non-aqueous solvent and a supporting electrolyte has been used for the electrolysis in the electrooxidation.
