Abstract
The invention relates to new N-aryl-nitrogen heterocycles of the general formula (I) ##STR1## in which R.sup.1 represents hydrogen or halogen, R.sup.2 represents hydrogen or an in each case optionally substituted, straight-chain or branched radical from the series comprising alkyl, alkenyl or cycloalkyl and A represents one of the radicals or ##STR2## where R.sup.3 represents alkyl, R.sup.4 represents alkyl and R.sup.5 represents hydrogen or alkyl, a plurality of processes for their preparation, and their use as herbicides.
Claims12
An N-aryl-nitrogen heterocycle of the formula ##STR31## wherein R.sup.1 represents hydrogen, fluorine, chlorine, bromine or iodine,
- R.sup.2 represents hydrogen or a straight-chain or branched radical selected from the group consisting of alkyl, halogenoalkyl having identical or different halogen atoms, alkoxyalkyl, alkoxyalkoxyalkyl, alkoxycarbonylalkyl, alkenyl, or cycloalkyl which is optionally monosubstituted or polysubstituted by identical or different straight-chain or branched alkyl substituents and
- A represents one of the radicals ##STR32## where R.sup.3 represents straight-chain or branched alkyl,
- R.sup.4 represents straight-chain or branched alkyl,
- R.sup.5 represents hydrogen or straight-chain or branched alkyl.
An N-aryl-nitrogen heterocycle of the formula (Ia) ##STR39## wherein R.sup.1 represents hydrogen or halogen,
- A represents one of the radicals ##STR40## where R.sup.3 represents alkyl,
- R.sup.4 represents alkyl and
- R.sup.5 represents hydrogen or alkyl.
