Process for the preparation of 3,6-disubstituted 4-amino-1,2,4-triazin-5-ones |
| abstract |
The herbicidally active 3,6-substituted 4-amino-1,2,4-triazin-5-ones of the general formula in which R 1 and R 2 have the meaning given in the description are obtained in good yields by a new, two-stage cyclization reaction if a-ketocarboxamides of the formula with hydrazidines of the formula optionally in the presence of a diluent at temperatures between 0 and 150 ° C., a condensation reaction to open-chain condensation products taking place in the first process stage and an elimination reaction with ring closure to the end products (I) taking place in the second process step. |
