| 摘要 |
The invention relates to novel pyrazolylpyrrolinones of the formula (I) <IMAGE> in which R<1> represents hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, alkoxyalkyl, or in each case optionally substituted aralkyl or aryl, R<2> represents hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, alkoxyalkyl, alkylthioalkyl, or represents optionally substituted cycloalkyl or optionally substituted aryl, R<3> represents hydrogen or alkyl, R<4> and R<5> either independently of one another in each case represent hydrogen or alkyl or together represent an alkanediyl, alkenediyl or alkdienediyl radical, each of which is divalent, and R<6> represents halogen, hydroxyl, mercapto, amino, alkylamino, dialkylamino, a radical <IMAGE> or a radical R<8>-SO2-O-, to a plurality of processes and novel intermediates for their preparation, and to their use as herbicides. |
