Abstract
NEW MATERIAL:Pyrazole derivatives of formula I: (R1 and R2 are lower alkyl groups; X is halogen, nitro, or cyano group; Y is lower alkyl, or lower alkoxy group; m is 1 or 2; n is 1,2, or 3).
EXAMPLE: 1,3-Dimethyl-4-(2,4-dichlorobenzoyl)-5-(4-methylbenzoylmethoxy) pyrazole.
USE: Herbicides capable of protecting crops, e.g. rice plants, etc. against harmful weeds, e.g. barnyard grass, chufa, etc. without doing substantial damages to the crops.
PROCESS: Compounds of formula II are reacted with compounds of formula III: (Hal is halogen) in a solvent in the presence of an alkaline substance, e.g. potassium carbonate, etc. to give the compounds of formula I. Alternatively, compounds of formula IV are reacted with compounds of formula III under the same conditions as described above to form compounds of formula V, which are then reacted with compounds of formula IV in a solvent in the presence of a catalyst, e.g. aluminum chloride, etc.
