The reductive electrodetosylation of N, N′-bis-(o-tosylaminophenyl) propanediamide was performed in an undivided cell fitted with a sacrificial aluminum anode, at constant current and at room temperature. The completion of the reduction process was favoured by the complexing effect of the anodically generated metal ion to form Al-N, N′-bis (o- aminophenyl) propanediamide. Finally, the N, N′-bis (o-aminophenyl) propanediamide ...
