Abstract

Herbicidal sulphonylaminocarbonyl-triazolinones having substituents which are bonded via sulphur, of the formula ##STR1## in which n represents the numbers 0, 1 or 2, PA0 R.sup.1 represents hydrogen, hydroxyl or amino, or represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, aralkyl, aryl, alkoxy, alkenyloxy, alkylamino, cycloalkylamino and dialkylamino, PA0 R.sup.2 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl and aryl, and PA0 R.sup.3 represents an optionally substituted radical from the series comprising alkyl, aralkyl, aryl and heteroaryl, as well as salts of compounds of the formula (I). Also new are the compounds of the following formula: ##STR2## in which n, R.sup.1 and R.sup.2 have the abovementioned meanings and PA0 Z represents halogen, alkoxy, aralkoxy or aryloxy.
