1-Alkyl-4-benzoyl-5-hydroxy-1H-pyrazole compounds in which the benzoyl moiety is substituted in the 2-position with groups such as halo or alkyl, in the 4- position with an alkylsulfonyl group, and in the 3-position with a cyclic or acyclic derivatized amino group, such as 1-ethyl-4-(2-chloro-4-methylsulfonyl- 3-(morpholin-4-yl)benzoyl-5-hydroxy-1h-pyrazole, were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The compounds can be applied either preemergently or postemergently and can be used to control undesirable vegetation in corn, rice, and wheat crops.
La présente invention concerne des composés 1-alkyl-4-benzoyl-5-hydroxy-1H-pyrazole dans lesquels le groupe fonctionnel benzoyle est substitué en position 2 par des groupes tels que halo ou alkyle, en position 4 par un groupe alkylsulfonyle, et en position 3 par un groupe amino dérivatisé cyclique ou acyclique tel que le 1-éthyl-4-(2-chloro-4-méthylsulfonyl-3)-(morpholin-4-yl)benzoyl-5-hydroxy-1H-pyrazole. Les composés ainsi obtenus s'avèrent convenir particulièrement à la lutte contre une variété de dicotylédone et de mauvaise herbe graminée. Ces composés, qui peuvent s'appliquer en traitement de prélevée ou en traitement de postlevée, conviennent à la lutte contre les plantes parasites du maïs, du riz et du blé.
