Abstract (en)
[origin: WO9812182A1] 1-sulfonyl-3-phenylpyrazoles having the formula (I) and their salts are disclosed. In the formula, R<1> is C1-C4-alkyl, C1-C4-alkyl halide; R<2> is C1-C4-alkyl, C1-C4-alkyl halide; R<3> is H, CN, halogen, C1-C4-alkyl; R<4> is H, halogen; R<5> is H, CN, NO2, halogen, C1-C4-alkyl, C1-C4-alkyl halide, C1-C4-alkoxy, C1-C4-alkoxy halide; X is a chemical bond, an optionally substituted methylene, ethylene, propan-1,3-diyl, ethen-1,2-diyl chain or an oxymethylene or thiamethylene chain bound to the phenyl ring by the heteroatom; R<6> is H, NO2, CN, halogen, SO2-halogen, -O-Y-R<8>, -O-CO-Y-R<8>, -N(Y-R<8>)(Z-R<9>), -N(Y-R<8>)-SO2-Z-R<9>, -N(SO2-Y-R<8>)(SO2-Z-R<9>), -N(Y-R<8>)-CO-Z-R<9>, -N(Y-R<8>)(O-Z-R<9>), -S-Y-R<8>, -SO-Z-R<8>, -SO2-Y-R<8>, -SO2-O-Y-R<8>, -SO2-N(Y-R<8>)(Z-R<9>), -CO-Y-R<8>, -C(=NOR<10>)-Y-R<8>, -(=NOR<10>)-O-Y-R<8>, -CO-O-Y-R<8>, -CO-S-Y-R<8>, -CO-N(Y-R<8>)(Z-R<9>), -CO-N(Y-R<8>)(O-Z-R<9>), -PO(O-Y-R<8>)2; R<7> is H, or R<5> + XR<6> or XR<6> + R<7> form, together with the C atoms of the phenyl ring which interconnect them, an annulated, optionally substituted carbocyclic or 5-/6-membered heterocyclic ring with 1-3 heteroatoms, whereas the cycle may also contain 1 or 2 CO-, CS- or SO2 ring members. These compounds are useful as herbicides, and for desiccating/defoliating plants.
