operationally simple oxidation–cyanation method for the synthesis of cyanamides is described. The procedure utilizes inexpensive and commercially available N-chlorosuccinimide and Zn(CN)2 as reagents to avoid direct handling of toxic cyanogen halides. It is demonstrated to be amenable for the cyanation of a variety of primary and secondary amines and aniline derivatives as well as a complex synthetic

Transition metal-free electrochemical approaches for the N-cyanation of secondaryamines and the α C-cyanation of tertiaryamines have been well established, with products being obtained in moderate to good yields and with good functional group tolerance under ambient conditions. The synthetic application of the protocols has been highlighted through scale-up experiments in a galvanostatic mode. Preliminary
Copper-promoted N-cyanation of aliphatic sec-amine by CuCN is achieved via oxidative coupling. This procedure employs O2 as a clean oxidant. Notably, sulfoximines and 1,1,3,3-tetramethylguanidine also worked well in this procedure. Thus, it represents a key progress in the C–N bond formation reaction as well as in the cyanation reaction.
