Most disubstituted cyanamides exhibit a very low cathodic activity and are therefore difficult to reduce.However, the cathodic cleavage of diarylcyanamides can be carried out directly and leads to the corresponding diarylamine; the action of sodium causes the same cleavage.Alkylarylcyanamides display no cathodic step, but can be reduced indirectly by redox catalysis; this allows the determination of the standard potential corresponding to the first electron transfer.The macroscale electrolysis, in the presence of the catalyst, leads to the alkylarylamine by cleavage, whereas the action of sodium gives mainly a cyanoguanidine.Dialkylcyanamides are electroreducible neither directly, nor indirectly, whereas by action of sodium they trimerize almost quantitatively into triazines. Key words: cyanamide, decyanation, electroreduction, redox catalysis.
