2,3-diaminoacrylonitrile derivatives or their salts, having the formula (I) in which R represents an alkyl group which can be substituted by (substituted or unsubstituted phenyl groups, halogen atoms, C1-6 alkoxycarbonyl groups, carboxy groups, C1-6 alkylthio groups C1-6 alkoxycarbonyl, hydroxy groups, mercapto groups, cycloalkyl groups or heterocyclic groups containing oxygen atoms), an alkenyl group, a cycloalkyl group, an aryl group which may be substituted by (halogen atoms, C1-6 alkyl groups, nitro groups, substituted or unsubstituted phenyl or phenoxy groups or heterocyclic groups containing oxygen atoms or sulfur atoms). These 2,3-diaminoacrylonitrile derivatives can be used as starting materials for the production of pharmaceutical and / or agricultural intermediates such as cyanoimidazoles, cyanopyrazines or other cyano substituted heterocycles. |
