| abstract |
The invention concerns sulphonylamino(thio)carbonyltriaxolin(thi)ones of formula (I) in which Q1 is oxygen or sulphur, Q2 is oxygen or sulphur, Q3 is oxygen or sulphur, R1 is hydrogen, hydroxy, amino, alkylidenamino or an optionally substituted group from the series alkyl, alkenyl, alkinyl, alkoxy, alkylamino, dialkylamino, alkanoylamino, cycloalkyl, cycloalkylalkyl, cycloalkylamino, aryl and arylalkyl, R2 is substituted aryl when Q3 is oxygen and R2 is optionally substituted aryl when Q3 is sulphur, and R3 is an optionally substituted group from the series alkyl, arylalkyl, aryl and heteroaryl, plus salts of such compounds. The invention also concerns methods of preparing compounds of formula (I), intermediates for use in their preparation and the use of the compounds as herbicides. |
