"BENZILIDENOPIRAZOLONE, COMPOSITION, PROCESSES FOR THE PREPARATION OF HERBICIDALLY ACTIVE COMPOSITIONS, TO CONTROL UNWANTED VEGETATION AND FOR THE PREPARATION OF BENZILIDENOPIRAZOLONES, AND, BENZOILPIRAZOL". Benzylidenopyrazolones of formula (I): wherein the substituents and the index n have the following meanings: R¹ is optionally substituted C ~ 1 ~ -C ~ 6 ~ -alkyl; R² is optionally substituted C ~ 1 ~ -C ~ 6 ~ -alkyl, optionally substituted C ~ 1 ~ -C ~ 6 ~ -alkoxy, halogen, nitro, cyano; R³ is hydrogen, halogen, nitro, cyano, a group NR ^ 5 ^ R ^ 6 ^, OCOR ^ 5 ^, NR ^ 5 ^ COR ^ 6 ^, CO ~ 2 ~ R ^ 5 ^, -COSR ^ 5 ^, -CONR ^ 5 ^ R ^ 6 ^, C ~ 1 ~ -C ~ 4 ~ -alkoxyiminoalkyl, C ~ 1 ~ -C ~ 6 ~ -alkylcarbonyl, C ~ 1 ~ -C ~ 6 ~ -alkyl optionally substituted, C ~ 1 ~ -C ~ 6 ~ -alkoxy optionally substituted, C ~ 1 ~ -C ~ 6 ~ -alkylthio optionally substituted, C ~ 2 ~ -C ~ 6 ~ -alkenyl optionally substituted, C ~ 2 ~ -C ~ 6 ~ - optionally substituted alkynyl, optionally substituted phenyl, optionally substituted phenoxy, an optionally substituted 5- or 6-membered saturated or unsaturated heterocycle, which may contain up to 4 nitrogen atoms and / or up to 2 oxygen or sulfur atoms as ring members; R 4 is C ~ 1 ~ -C ~ 6 ~ -alkyl, C ~ 1 ~ -C ~ 4 ~ -haloalkyl; or R³, R ^ 4 ^ form an optionally substituted, saturated or unsaturated, 2 or 3-membered bridge, which may contain a sulfur atom that can be oxidized to the sulfoxide or sulfone; R 5 is hydrogen or optionally substituted C ~ 1 ~ -C ~ 6 ~ -alkyl; R6 6 is optionally substituted C ~ 1 ~ -C ~ 6 ~ -alkyl; R 7 is hydrogen, C ~ 1 ~ -C ~ 6 ~ -alkyl or C ~ 1 ~ -C ~ 4 ~ -haloalkyl; n is 0, 1 or 2; X is hydrogen, chlorine or bromine; the claimed compounds may be present either in the trans form or in the cis form, or as a mixture of these isomers. |
