Abstract

NEW MATERIAL:A compound of formula I: [R1 is H, lower alkyl group, etc.; R2 is H, lower alkenyl group, etc.; X is halogen, nitro, etc.; Y is O or S; Z is lower alkyl or A-B (A is lower alkylene; B is lower alkoxy or benzyloxy group); n is an integer 1W4].
EXAMPLE: 4-(2-chlorobenzoyl)-1,3-dimethyl-5-methoxypyrazole.
USE: Herbicides capable of destroying perennial weeds, e.g. umbrella plants, in paddy fields which will be easily destroyed by ordinary herbicides, or strong weeds in plowed fields without damage to crops, preferably applied to plowed fields in 10W 50g per are.
PROCESS: A compound of formula II is alkylated with an alkylating agent corresponding to Z, particulary a halide, in a solvent, e.g. benzene or dioxane, at room temperature to the refluxing temperature of the solvent to give the compound of formula I. Preferably, Na2CO3 is used as a deacidification agent when a halide is used.
