Literature References
One-carbon fragment which can behave as a nucleophile or an electrophile. Alkylating agents give N,N-dialkyl cyanamides which readily undergo hydrolysis to dialkylamines: Synthesis, 882 (1978). Useful building block for heterocyclic synthesis. Reaction with o-phenylenediamines gives 2-aminobenzimidazoles: Angew. Chem. Int. Ed., 12, 841 (1973). With 4-(1-Cyclohexen-1-yl)morpholine, B22004, and elemental sulfur, a 2-aminothiazole is formed in good yield: J. Prakt. Chem., 312, 776 (1970): In the presence of NBS, undergoes addition to alkenes. The products are converted to N-cyanoaziridines by base: Tetrahedron Lett., 1125 (1970), or in the presence of acid, cyclization gives an imidazoline, which can be converted to the vic-diamine: J. Am. Chem. Soc., 105, 4106 (1983); Tetrahedron Lett., 25, 399 (1984):
Applications
Cyanamide is used as an intermediate in the production of pharmaceuticals and other organic compounds. It is also used as an alcohol deterrent drug. It is widely used as plant growth regulator, agrochemical and fertilizer.
