Process for the preparation of 4-substituted-1-aryl-5-amino-pyrazoles |
| abstract |
A new process for the preparation of partially known, insecticidally and herbicidally active 4-substituted 1-aryl-5-amino-pyrazoles of the general formula (I) provided, in which R¹ represents hydrogen or alkyl, R² represents alkyl or haloalkyl and Ar stands for multiply substituted phenyl or pyridyl.n n n The compounds of the formula (I) are obtained if arylhydrazine hydrohalides of the formula (II) Ar-NH-NH₂ x HHal (II) in which Hal stands for halogen and Ar has the meaning given above, with acrylonitrile derivatives of the formula (III), in which R¹ and R² have the meaning given above and R³ and R⁴ are each independently alkyl or phenyl or R³ and R⁴ together with the nitrogen atom to which they are attached represent a saturated heterocycle, optionally in the presence of a diluent at temperatures between 60 ° C and 90 ° C. |
