Claims
- 1. A 2,3-diaminoacrylonitrile derivative having the formula ##STR59## wherein R represents on C.sub.1-18 alkyl group (which may be substituted by unsubstituted or substituted phenyl groups, halogen atoms, C.sub.1-4 alkoxycarbonyl groups, C.sub.1-2 alkoxycarbonyl C.sub.1-2 alkylthio groups, hydroxy groups, mercapto groups or heterocyclic groups containing oxygen and sulfur atoms); an C.sub.3-15 alkenyl group; a C.sub.5-6 cycloalkyl group; a naphthyl group; a benzofuranyl group; or a phenyl group (which may be substituted by halogen atoms, C.sub.1-4 alkyl groups, cycloalkyl groups, nitro groups, unsubstituted or substituted phenyl or phenoxy groups).
- 2. A process for the production of a 2,3-diaminoacrylonitrile derivative or salts thereof having the formula ##STR60## which comprises reacting hydrogen cyanide with a compound having the formula RSSR in the presence of a base at 0.degree.-40.degree. C., wherein the molar ratio of RSSR: base: hydrogen cyanide is at least 1:1:1; wherein R represents an C.sub.1-18 alkyl group (which may be substituted by unsubstituted or substituted phenyl groups, halogen atoms, C.sub.1-4 alkoxycarbonyl groups, carboxy groups, C.sub.1-2 alkoxycarbonyl C.sub.1-2 alkylthio groups, hydroxy groups, mercapto groups or heterocyclic groups containing oxygen and sulfur atoms); an C.sub.3-15 alkenyl group; a C.sub.5-6 cycloalkyl group; a naphthyl group; a benzofuranyl group; or a phenyl group (which may be substituted by halogen atoms, C.sub.1-4 alkyl groups, cycloalkyl groups, nitro groups, unsubstituted or substituted phenyl or phenoxy groups).
- 3. A process for the production of a 2,3-diaminoacrylonitrile derivative or salts thereof having the formula ##STR61## which comprises reacting 2-aminomalononitrile with a compound having the formula RSSR, RSH or RSC--CH.sub.3 in the presence of a base wherein R represents an C.sub.1-18 alkyl group (which may be substituted by unsubstituted or substituted phenyl groups, halogen atoms, C.sub.1-4 alkoxycarbonyl groups, carboxy groups, C.sub.1-2 alkoxycarbonyl C.sub.1-2 alkylthio groups, hydroxy groups, mercapto groups or heterocyclic groups containing oxygen and sulfur atoms); an C.sub.3-15 alkenyl group; a C.sub.5-6 cycloalkyl group; a naphthyl group; a benzofuranyl group; or a phenyl group (which may be substituted by halogen atoms, C.sub.1-4 alkyl groups, cycloalkyl groups, nitro groups, unsubstituted or substituted phenyl or phenoxy groups).
- 4. The process of claim 2, wherein the molar ratio of RSSR: base: hydrogen cyanide is 1:2:6.
- 5. The process of claim 2, wherein the reaction is carried out at a temperature range from 5.degree.-20.degree. C.
