ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to new substituted aromatic amino compounds, the processes for their preparation, and to their use as herbicides.
Some substituted aromatic amino compounds such as, for example, N-[2-(1,5-dihydro-1-methyl-5-thioxo-3-trifluoromethyl-4H-1,2,4-triazol-4-yl)-5-fluorophen-yl]-benzamide and N-[5-chloro-2-(1,5-dihydro-1-methyl-5-thioxo-3-trifluoromethyl-4H-1,2,4-triazol-4-yl)-phenyl]-acetamide have already been disclosed in the patent literature as candidate herbicides (cf. U.S. Pat. No. 5,108,486). However, these compounds have not gained any particular importance.
Other substituted aromatic amino compounds such as, for example, N-[5-chloro-2-(2,5-dihydro-3,4-dimethyl-2,5-dioxo-1H-pyrrol-1-yl)-phenyl]-acetamide (cf. Indian J. Chem, Sect. B, 29B (1990), 659-660—cited in Chem. Abstracts 113:211906) and N-[2-(5-diethylamino-3-t-butyl-1H-1,2,4-triazol-1-yl)-5-trifluoromethyl-phenyl]-2,2-dimethyl-propanamide and N-[2-(5-diethylamino-3-t-butyl-1H-1,2,4-triazol-1-yl)-5-trifluoromethyl-phenyl]-acetamide (cf. JP 02091062—cited in Chem. Abstracts 113:97612) are also known already. However, nothing has been disclosed about the herbicidal activity of these compounds.

, R

and R

or R
8
and R

—together represent alkanediyl (alkylene) or oxaalkanediyl, and
where the individual radicals R
8
and R
9
—if they occur more than once in the same heterocyclic group, may have identical or different meanings within the scope of the above definition,
with the exception of the prior-art compound N-[5-chloro-2-(2,5-dihydro-3,4-dimethyl-2,5-dioxo-1H-pyrrol-1-yl)-phenyl]-acetamide (cf. Indian J. Chem, Sect. B, 29B (1990), 659-660—cited in Chem. Abstracts 113:211906), and of N-[2-(5-diethylamino-3-t-butyl-1H-1,2,4-triazol-1-yl)-5-trifluoromethyl-phenyl]-2,2-dimethyl-propanamide and N-[2-(5-diethylamino-3-t-butyl-1H-1,2,4-triazol-1-yl)-5-trifluoromethyl-phenyl]-acetamide (cf. JP 02091062—cited in Chem. Abstracts 113:97612), which are also prior-art compounds.
The new substituted aromatic amino compounds of the general formula (I) are obtained when aromatic amino compounds of the general formula (II)
in which
R
3
, R

X represents halogen,
if appropriate in the presence of an acid acceptor and if appropriate in the presence of a diluent,
and the resulting compounds of the general formula (I) are converted into other compounds of the general formula (I) in accordance with the above definition (cf. the preparation examples), if appropriate by customary methods.
The new substituted aromatic amino compounds of the general formula are distinguished by a potent and selective herbicidal activity.
In the definitions, the saturated or unsaturated hydrocarbon chains, such as alkyl, alkanediyl, alkenyl or alkinyl—also in connection with hetero atoms, such as in alkoxy, alkylthio or alkylamino—are in each case straight-chain or branched.
