1-(2-OXYAMINOSULPHONYLPHENYLSULPHONYL)-3-TRIAZINYL-UREAS,THEIR PREPARATION AND THEIR USE AS HERBICIDES

摘要

The invention relates to novel 1-(2- oxyaminosulphonylphenylsulphonyl)-3-triazinylureas of the formula (I) IMAGE in which R1 represents an optionally substituted radical from the series comprising alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aralkyl and aryl, R2 represents hydrogen, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C1-C4-alkyl [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkoxy [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkylthio [which is optionally substituted by fluorine and/or chlorine], amino, C1-C4-alkyl- or di-(C1-C4-alkyl)-amino [which are optionally substituted by fluorine] and R3 represents hydrogen, fluorine, chlorine, bromine, hydroxyl, cyclopropyl, C1-C4-alkyl [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkoxy [which is optionally substituted by fluorine and/or chlorine], C1-C4-alkylthio [which is optionally substituted by fluorine and/or chlorine], amino, or C1-C4-alkyl- or di-(C1-C4-alkyl)-amino [which are optionally substituted by fluorine], their preparation, and their use as herbicides.u
