Abstract: New 1,2-dicyano-1-amino-2-(aminomethyleneamino) ethylene derivs. are cpds. of formula (I). In (I), R1 and R2 are (cyclo)aliphatic, araliphatic or aromatic residues for NR1R2 is a heterocyclic residue. (I) are prepd. by reaction of HC(NR1R2)(OR3)CN (III) with HCN. In (III), R3 is a (cyclo)aliphatic residue. The reaction is carried out at -50 to 120 degrees C (pref. -20 to 30 degrees C), advantageously in an inert solvent. (I) are useful as intermediates for dyes and pesticides.
