摘要:
The invention relates to new benzodisultams of the general formula (I) ##STR1## in which R.sup.1 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl,R.sup.2 represents hydrogen or an optionally substituted radical from the series comprising alkyl, alkemyl, alkinyl and aralkyl, andR.sup.3 represents an optionally substituted and/or optionally fused six-membered aromatic heterocyclic radical which contains at least one nitrogen atom,a process for their preparation and their use as herbicides.
摘要:

摘要:
Substituted 5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxyacetic acid amides of the formula ##STR1## in which R.sup.1 and R.sup.2 are identical or different and each represent alkyl, alkenyl, alkinyl, alkoxy, aralkyl, cycloalkyl, cycloalkenyl or aryl, each of which is optionally substituted, or a nitrogen-containing heterocyclic radical, or, together with the nitrogen atom to which they are bonded, form an optionally substituted, optionally partially unsaturated and optionally benzo-fused monocyclic or bicyclic structure which optionally contains further hetero atoms, with the proviso that R.sub.1 does not represent methyl when R.sup.2 represents phenyl, which possess herbicidal activity.
