HERBICIDES COMPRISING SUBSTITUTED 5-(ACYLAMINO)-1-PHENYL-PYRAZOLE DERIVATIVES AND ACTIVE INGREDIENT AND PROCESS FOR PRODUCING SUBSTITUTED 5-(ACYLAMINO)-1-PHENYL-PYRAZOLE DERIVATIVES

摘要

A 5-aminopyrazole of the formula in which R1 represents alkoxycarbonyl, alkenyloxycarbonyl or alkinyloxycarbonyl, and R3, R4, R5, R6, and R7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbonyl or a radical -(X)n-R8 wherein X represents oxygen, sulphur, sulphinyl or sulphyonyl, n represents 0 or 1 and R8 represents halogenoalkyl, with the proviso that at least one of the radicals R3, R4, R5, R6 or R7 represents a radical -(X)n-R8, and R1 does not represent cyano if R1 represents trifluoromethyl, These compounds are intermediates useful in the preparation of herbicidally active substituted 5-acylamino-1-phenylpyrazoles.
