Abstract

Herbicidally active novel benzodisultams of the formula ##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, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C.sub.1 -C.sub.4 -alkyl (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.4 -alkoxy [which is optionally substituted by fluorine and/or chlorine], C.sub.1 -C.sub.4 -alkylthio (which is optionally substituted by fluorine and/or chlorine), amino, or C.sub.1 -C.sub.4 -alkyl- or di-(C.sub.1 -C.sub.4 -alkyl)-amino (which is optionally substituted by fluorine) and R.sup.3 represents hydrogen, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C.sub.1 -C.sub.4 -alkyl (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.4 -alkoxy (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.4 -alkylthio (which is optionally substituted by fluorine and/or chlorine), amino or C.sub.1 -C.sub.4 -alkyl- or di-(C.sub.1 -C.sub.4 -alkyl)-amino (which is optionally substituted by fluorine).

A benzodisultam of the formula ##STR35## in which R.sup.1 represents C.sub.1 -C.sub.12 -alkyl (which is optionally substituted by fluorine, chlorine, cyano, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -alkylsulphinyl, C.sub.1 -C.sub.4 -alkylsulphonyl, C.sub.1 -C.sub.4 -alkyl-carbonyl, C.sub.1 -C.sub.4 -alkoxy-carbonyl, C.sub.1 -C.sub.4 -alkylamino-carbonyl or di-(C.sub.1 -C.sub.4 -alkyl)-aminocarbonyl), C.sub.3 -C.sub.6 -alkenyl (which is optionally substituted by fluorine, chlorine or bromine), C.sub.3 -C.sub.6 -alkinyl, C.sub.3 -C.sub.6 -cycloalkyl, C.sub.3 -C.sub.6 -cycloalkyl-C.sub.1 - or C.sub.2 -alkyl, phenyl-C.sub.1 - or C.sub.2 -alkyl (which is optionally substituted by fluorine, chlorine, nitro, cyano, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -alkoxy-carbonyl) or phenyl (which is optionally substituted by fluorine, chlorine, nitro, cyano, C.sub.1 -C.sub.4 -alkyl, trifluoromethyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 - or C.sub.2 -fluoroalkoxy, C.sub.1 -C.sub.4 -alkylthio, trifluoromethylthio or C.sub.1 -C.sub.4 -alkoxy-carbonyl),

R.sup.2 represents hydrogen, fluorine, chlorine, hydroxyl, cyclopropyl, methyl (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.3 -alkoxy (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.3 -alkylthio (which is optionally substituted by fluorine and/or chlorine), amino, C.sub.1 -C.sub.3 -alkyl- or di-(C.sub.1 -C.sub.3 -alkyl)-amino (which is optionally substituted by fluorine) and
R.sup.3 represents hydrogen, fluorine, chlorine, hydroxyl, cyclopropyl, methyl (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.3 -alkoxy (which is optionally substituted by fluorine and/or chlorine), C.sub.1 -C.sub.3 -alkylthio (which is optionally substituted by fluorine and/or chlorine) amino, or C.sub.1 -C.sub.3 -alkyl or di-(C.sub.1 -C.sub.3 -alkyl)amino (which is optionally substituted by fluorine).
