    Abstract: The invention relates to cycloalkyl-substituted benzoyl pyrazoles of formula (I) wherein said variables can, for example, have the following meanings: R1 = hydrogen, nitro, halogen, cyano, rhodano or an optionally substituted aliphatic radical; R2 = an optionally substituted aliphatic radical, halogen , nitro, in addition to substituted sulfonyl or amino groups; R3 = hydrogen, halogen, C1-C6-alkyl, C1-C6-halogenalkyl, C1-C6-alkoxy, C2-C6-alkenyl or C2- C6- alkinyl; R4, R5 = hydrogen, nitro, halogen, cyano, rhodano, an optionally substituted aliphatic radical or substituted sulfonyl or amino groups; R6 = hydrogen, halogen, C1-c6-alkyl, C1-C6-alkoxy, C3-C8-cycloalkyl; R7 = a cycli c ring system with 3 - 14 ring atoms; R16 = hydroxy or a substituted hydroxy group; in addition to tautomers or agriculturally useful salts thereof. The invention also relates to methods for the production of compounds of formula (I), agents containing said compounds, the use of compounds of formula (I) a nd agents containing said compounds as herbicides.

    Abstract: The invention relates to a method for producing substituted hydroxypyrazoles and new intermediate products. It relates in particular to a method for producing compounds of formula (I) in which R1 is hydrogen, an aliphatic gro up with between 1 and 8 carbon atoms, C1-C6-alkoxycarbonyl, C1-C6-alkyl thiocarbonyl or a cyclic ring system with between 3 and 14 ring atoms; R2 is hydrogen, an aliphatic group with between 1 and 8 carbon atoms; or R1 and R2 together with the carbon atom to which they are bound are a cyclic or bicycl ic ring system with between 3 and 14 ring atoms. Said method comprises the production, as starting or intermediate products, of compounds of formula (I I) in which R3 and R4 are readily cleavable groups and R1 and R2 have the meanings given above. Said compounds are cyclized under suitable reaction conditions to yield compounds of formula (I).
