A process for preparing a 2-R.sub.3 -3-(cyanoimino)-3-(amino)propionitrile which comprises A. reacting a mineral acid addition salt of a 2-cyanoacetimidate of the formula ##STR1## with cyanamide in an organic solvent to form a N,2-dicyanoacetimidate B. REACTING A N,2-dicyanoacetimidate of the formula ##STR2## with an amine of the formula ##STR3## to form a 2-R.sub.3 -3-(cyanoimino)propionitrile of the formula ##STR4## N,2-dicyanoacetimidate compounds are claimed as well.
制备2-R.sub.3 -3-(氰亚胺基)-3-(氨基)丙腈的方法包括:A.在有机溶剂中反应式为##STR1##的2-氰基乙酰亚胺酸盐和氰胺,形成N,2-二氰基乙酰亚胺酸盐;B.将式为##STR2##的N,2-二氰基乙酰亚胺酸盐和式为##STR3##的胺反应,形成式为##STR4##的2-R.sub.3 -3-(氰亚胺基)丙腈。本发明还涉及N,2-二氰基乙酰亚胺酸盐化合物。
