HETAROYL CYCLOHEXANEDIONE DERIVATIVES WITH HERBICIDAL EFFECT

摘要

Hetaroyl derivatives having the formula (I) are disclosed, as well as their salts useful in agriculture. In the formula, the variables have the following meanings: R1, R2 are hydrogen, nitro, halogen, cyano, rhodano, hydroxy, mercapto, optionally substituted and/or functionalised C1-C6 alkyl, C1-C6 alkoxy, C1-C6 alkylthio, C1-C6 alkylsulfinyl, C1-C6 alkylsulfonyl, C1-C6 alkoxysulfonyl, or optionally substituted phenyl, phenoxy, phenylthio, phenylsulfinyl or phenylsulfonyl; Z is an optionally substituted, 4-membered, unsaturated, partially or completely saturated chain with three carbon atoms and one nitrogen atom; and Q is optionally substituted cyclohexan-1,3-dione linked at position 2. Also disclosed is a process for preparing the hetaroyl derivatives, agents containing the same, as well as the use of these derivatives or the agents containing the same for controlling undesirable plants.
