Donetti, Arturo published the artcileMild and effective two-step conversion of disubstituted cyanamides to secondary amines, SDS of cas: 2451-91-4, the publication is Journal of Organic Chemistry (1972), 37(21), 3352-3, database is CAplus.
A convenient procedure was developed to convert disubstituted cyanamides into secondary amines under mild conditions. Disubstituted cyanamides, R2NCN were obtained from the halides and Na cyanamide in Me2SO. Equimolar amounts of R2NCN and KCN refluxed in MeOH, gave the intermediate o-methylisoureas, which were hydrolyzed to secondary amines with dilute HOAc.
Journal of Organic Chemistry published new progress about 2451-91-4. 2451-91-4 belongs to amides-buliding-blocks, auxiliary class Nitrile,Amine,Benzene, name is N,N-Dibenzylcyanamide, and the molecular formula is C15H14N2, SDS of cas: 2451-91-4.
