Certain new 1-(substituted-hydrocarbyl)-di- and trihalopyrazoles have been synthesized. They possess herbicidal and plant growth regulatory activity. The hydrocarbyl group, i.e., alkylene or alkenylene group at the 1-nitrogen of the pyrazole nucleus has either a carboxyl group, an hydroxymethyl group, an hydroxymethyl lower-alkanoate group, a carboxylic lower-alkyl ester group, a cyano group, or a carboxylic amide group. The new compounds are prepared and isolated by conventional chemical reactions and procedures. An improved reaction for making the new carboxylic acids is described. Weed control methods and compositions for herbicidal use are also described.
已经合成了某些新的1-(取代烃基)二元和三元卤代吡唑。它们具有除草和植物生长调节活性。在吡唑环的1-氮上的烃基,即烷基或烯基,具有羧基、羟甲基、羟甲基较低烷酸酯基、羧酸较低烷基酯基、氰基或羧酸酰胺基。新化合物通过常规的化学反应和程序制备和分离。描述了制备新羧酸的改进反应。还描述了除草用的杂草控制方法和组合物。
