Pyrazole derivative and herbicidal composition

FIELD OF THE INVENTION
The present invention relates to a novel pyrazole derivative and a herbicide comprising the derivative as an active ingredient.
BACKGROUND OF INVENTION
Specific pyrazole derivatives having herbicidal activity are known, for example from JP-A-55-113706. However, they have at 5-position of their pyrazole rings a hydroxyl group or a derivative thereof and consequently have chemical structures completely different from the compounds of the present invention.
In Chemische Berichte, 100 (9), 2885-98 (1967), methyl o-[(3-phenylpyrazol-4-yl)carbonyl]benzoate and o-[(3-phenylpyrazol-4-yl)carbonyl]benzoic acid are described. However, they have carboxylic acid methyl ester or carboxylic acid respectively as a substituent on their benzoyl groups and consequently have chemical structures different from the compounds of the present invention. In addition, no herbicidal activity is referred to in the same publication.
In Journal of Heterocyclic Chemistry, 19, 1355 (1982), 4-benzoyl-1-methyl-5-phenylpyrazole and 4-benzoyl-1-methyl-3-phenylpyrazole are described. However, they have a methyl group as a substituent at 1-position of their pyrazole rings and consequently have chemical structures different from the compounds of the present invention. In addition, no herbicidal activity is referred to in the same publication.
In U.S. Pat. No. 2,721,143, phenylpyrazole derivatives are described. However, they have chemical structures different from the compounds of the present invention. In addition, no herbicidal activity is referred to in the same publication.
In EP-A-538156, phenylpyrazole derivatives comprising a benzoyl group are claimed, which, however, are not concretely disclosed. In addition, no herbicidal activity is referred to in the same publication.

EXAMPLE 1
Synthesis of 4-(2-chlorobenzoyl)-3-phenylpyrazole (Compound No. 1) ##STR5##
Sodium hydride (3.15 g) which had been washed with n-hexane was suspended in tetrahydrofuran (100 ml), and to this methyl benzoate (8.58 g) and 18-crown-6-ether (0.07 g) were added at room temperature and then a solution of o-chloroacetophenone (5.03 g) and three drops of methanol was added dropwise. After stirring for 10 minutes at room temperature, the temperature of the reaction mixture was allowed to increase gradually, and then the mixture was refluxed for 2 hours. After allowing the reaction mixture to cool, it was poured into ice-water, acidified by adding diluted hydrochloric acid, extracted with ethyl acetate, washed with aqueous saturated sodium chloride and dried on anhydrous sodium sulfate, and then the solvent was distilled off. The resulting residue was added with n-hexane (50 ml), diethyl ether (50 ml) and a solution of sodium hydroxide and vigorously stirred for 30 minutes. The organic layer was removed and the aqueous layer was washed with a n-hexane/diethyl ether mixture solvent. This was acidified by adding diluted hydrochloric acid, extracted with benzene, dried on anhydrous sodium sulfate, and then the solvent was distilled off. The resulting residue was dissolved in benzene and filtrated through silica gel, and then the solvent was distilled off to give the compound of interest, 1-(2-chlorophenyl)-3-phenyl-1,3-propanedione (6.14 g) as a reddish brown solid.
