SULPHONYL AMINO(THIO)CARBONYL-1,2,4-TRIAZOLIN(THI)ONE DERIVATIVES, THE PRODUCTION THEREOF AND THE USE THEREOF AS HERBICIDES

The invention relates to sulphonyl amino(thio)carbonyl triazolin(thi)ones of formula (I) in which Q1 is oxygen or sulphur, Q2 is oxygen or sulphur, R1 is hydrogen, hydroxy, amino, alkylidenamino or a possibly substituted radical from the group alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy, alkylamino, dialkylamino, alkanoylamino, cycloalkyl, cycloalkylamino, cycloalkylalkyl, aryl and arylalkyl, R2 is hydrogen, hydroxy, mercapto, amino, halogen or a possibly substituted radical from the group alkyl, alkenyl, alkinyl, alkoxy, alkenyloxy, alkinyloxy, alkylthio, alkenylthio, alkinylthio, alkylamino, alkenylamino, alkinylamino, dialkylamino, alkanoylamino, aziridino, pyrrolidino, piperidino, morpholino, cycloalkyl, cycloalkenyl, cycloalkyloxy, cycloalkylthio, cycloalkylamino, cycloalkylalkyl, cycloalkylalkoxy, cycloalkylalkylthio, cycloalkylalkylamino, aryl, arylalkyl, aryloxy, arylalkoxy, arylthio, arylalkylthio, arylamino and arylalkylamino, or R1 and R2 together are possibly branched alkandiyl, and R3 is possibly substituted aryl, arylalkyl or heteroaryl, provided that either Q1 or Q2 is or both are sulphur. The invention also relates to salts of the compounds of formula (I), and also a process for producing the novel compounds of formula (I) and their salts and the use of these compounds as herbicides, and their intermediate compounds of formula (IV) in which Z is halogen, alkoxy, aryloxy or arylalkoxy.
