Abstract

NEW MATERIAL:A pyrazole derivative of formula I (X and Y are H, halogen, or methylsulfonyl, provided that at least one of X and Y is methylsulfonyl; Z is lower alkyl; R is 2,4-dinitrophenyl, benzyl, phenacyl, or pivaloylmethyl).
EXAMPLE: 1,3-Dimethyl-4-( 2-chloro-4-methylsulfonylbenzoyl )-5-(pivaloylmethoxy) pyrazole.
USE: Herbicide effective to harmful weeds such as barnyard grass and umbrella sedge, and essentially harmless to the crop such as rice plant.
PROCESS: The rearrangement reaction of a compound of formula II affords a compound of formula III, which is reacted with a compound of formula Hal-R in a solvent such as methyl ethyl ketone in the presence of an alkaline substance such as potassium carbonate to obtain the objective compound of formula I.
