Abstract
NEW MATERIAL:A compound shown by the formulaI(R1 is 1W6C alkyl, phenyl, substituted phenyl; R2 is H, 1W3C alkyl; R3 is H, 1W3C alkyl, 2W7C alkoxycarbonyl, cyano, etc.; R4 is 1W3C alkyl, aryl, 2W7C alkoxyalkyl, benzyl, substituted benzyl).
EXAMPLE: 1-Phenyl-5-(N-methyl-N-chloroacetylamino)pyrazole-4-carboxylic acid ethyl ester.
USE: A herbicide. Exhibiting improved herbicidal activity against weeds such as toothcup, Echinochloa crus-galli, Beauv. var. praticola Ohwi., harmful for the growth of rice plant, etc., having low toxicity, and safety, having strong herbicidal action on Amaranthus viridis L., Echinochloa crus-galli Beauv. var. praticola Ohwi., etc. by soil treatment before germination.
PROCESS: A chloroacetylaminopyrazole derivative shown by the formula II is reacted with a halogen compound shown by the formula III or a dialkyl sulfuric ester shown by the formula IV, to give a compound shown by the formulaI.
