A facile and general synthesis of various N-substituted cyanamides was accomplished by the Tiemann rearrangement of amidoximes with benzenesulfonyl chlorides (TsCl or o-NsCl) and DIPEA.

N-Allenyl cyanamides have been accessed via a one-pot deoxycyanamidation–isomerization approach using propargyl alcohol and N-cyano-N-phenyl-p-methylbenzenesulfonamide. The utility of this novel class of allenamide was explored through derivatization, with hydroarylation, hydroamination, and cycloaddition protocols employed to access an array of cyanamide products that would be challenging to access

energies and the entropies of activation have been determined for the hydrolysis of mono- and di-substituted cyanamides in 20% sulfuric acidsolution. The effect of substituents are distinctly shown in these kinetic data and the substituents are classified in three groups, (1) normal alkylgroup substituted, (2) branched alkylgroup substituted and (3) unsaturated group substituted cyanamides. The difference
