and the agriculturally useful salts thereof;
in particular alkali metal salts and ammonium salts.

The 3-heterocyclyl-substituted benzoyl derivatives of the formula I are obtainable by various routes, for example by the following
process:
Process A:
Reaction of pyrazoies of the formula II (where z - H) with an activated benzoic acid Ilia or a benxoic acid iltfi, which is preferably activated in situ to give the acylating product and subsequently subjecting the latter to a rearrangement reaction,*-



L! is a nucleophilically displaceable leaving group such as halogen, eg. bromine, chlorine, hetaryl, eg. imidazolyl, pyridyl, carboxylate, eg. acetate, trifluoroacetate, and the like.
The activated benzoic acid can be employed directly, as in the case of the benzoyl halides, or it can be prepared in situ, for example with dicyclohexylcarbodiimide, triphenylphosphine/azodicarboxylic aster, J-pyridine disulfide/triphenylphosphine, carbonyldiimidazole and the like".
It may be advantageous to carry out the acylation reaction in the presence of a base. The rcoctants and the auxiliary base are nxpediontly employed in equimolar amounts. A small excess of the auxiliary base, for example 1.2 to 1.5 mol equivalents based an II, may be advantageous under certain circumstances.
Suitable auxiliary bases are tertiary alkylamines, pyridine or alkali metal carbonates. Examples of solvents which can be used are chlorinated hydrocarbons such as methylene chloride, 1,2-dichloroethane, aromatic hydrocarbons such as toluene, xylene, chlorobenzene, ethers such as diethyl ether, methyl tfirt-butyl ether, tetrahydrofuran, dioxane, polar aprotic solvents such as acetonitrile, dimethylformamide, dimethyl sulfoxide, or esters such as ethyl acetate, or mixtures of these.
if benzoyl halides are employed as activated earboxylic acid component, it may be expedient to cool the reaction mixture to 0-lo°c when adding this reactant. The mixture is subsequently stirred at 20 - 100°C, preferably at 25 - 50*0, until the reaction is complete. WorK-up is carried out in the customary manner, for example the reaction mixture is poured into water and the product of value is extracted. Especially suitable solvents for this purpose are methylene chloride, diethyl ether and ethyl acetate-After the organic phase has been dried and the solvent removed, the crude ester can be employed without further purification for the rearT mgement reaction.
Rearrangement of the esters to give the compounds of the formula I is expediently carried out at from 20 to 40°c in a solvent and in the presence of a base and, if appropriate, with the aid of a
cyano compound as catalyst.

Examples of solvents which can be used are acetonitrile, methylene chloride, 1,2-dichloreth .ne, dioxane, ethyl acetate, toluene or mixtures of these. Preferred solvents are acetonitrile and dioxane.
Suitable bases are tertiary amines such triethylamine, pyridine, or alkali metal carbonates such as sodium carbonate, potassium carbonate, all of which are preferably employed in equimolar amounts or up to a fourfold excess, based on the ester. Triethylamine or alkali metal carbonate are preferably used, but by preference in a ratio of twice the equimolar amount based on the cpt.er.
Suitable cyano compounds are inorganic cyanides such as sodium cyanide, potassium cyanide, and organic cyano compounds such as acetone cyanohydrin, trimethylsilyl cyanide. They are employed in an amount: of I 'row 1 to 5fi mol p«rcant, baaed on Irm enter. Substances which are preferably employed are acetone cyanohydrin or trLmethylfiilyl cyanide, for example in an amount of from 5 to IS, preferably 10, mol percent, based on the ester.
work-up can bo effected in a manner known per se. For example, thn reaction mixture is acidified with dilute mineral acid, such as r>'t strength hydrochloric acid or sulfuric acid, and extracted with an organic solvent, eg. methylene chloride or ethyl acetate. The organic extract can be extracted with 5-10% strength alkali metal carbonate solution, eg. sodium carbonate or potassium -arbonate solution. The aqueous phase is acidified, and the precipitate which forms is filtered off with suction and/or extracted with methylene chloride or ethyl acetate, dried and concentrated.
(Examples of the synthesis of esters from hydroxypyrazoles and of the rearrangement of the esters are mentioned, for example, in EP-A 282 944 and US 4 643 757).
Process B:
Reaction of 3-heterocyclyl-substituted benzoyl derivatives of the formula I (where z » H) with a compound of the formula V
(where 2 = S02R17) :


L2 is a nucleophilically displaceable leaving group, such as halogen, ng, bromine, chlorine, hetaryl, eg. iinida20lyl, pyridyl, sulfonate, eg. OSO2R17.
The compounds of the formula V can be employed directly such as, for tsxample, in the case of the sulfonyl halides or sulfonic ^ anhydrides, or they can be prepared in situ, for example activated sulfonic acide [by means of sulfonic acid and dicyclobexylcarbodilmide, carbonyldiimidazole and tho lifcnj.
As a rule, the starting compounds are employed in an equimolar ratio. However, it may also be advantageous to employ an excess of one or the other component.
it may be advantageous to carry out the reaction in the presence o£ a base. The reactants and the auxiliary base are expediently empJoyed in ecnjimolar ratios. An excess of the auxiliary base, far example 1.5 to 3 mol equivalents, based on II, may be advantageous under certain circumstances.
Suitable auxiliary bases are tertiary alkylamines such as triethylamine or pyridine, alkali metal carbonates, eg. sodium carbonate or potassium carbonate, and alJcali metal hydrides, eg. sodium hydride. Triethylamine and pyridine are preferably used.

Examples of suitable solvents are chlorinated hydrocarbons sucn as methylene chloride or 1,2-dichlorethane, aromatic hydrocarbons, eg. toluene, xylene or chlorobenzene, ethers such as diethyl ether, methyl tert-butyl ether, tetrahydrrofuran or dioxane, polar aprotic solvents such as acetonitrile, dimethylformajnide or dimethyl sulfoxide, or esters such as ethyl acetate, or mixtures of these.

Finely distributing the mixture in 20,000 parts by weight of water gives a spray mixture which compriea 0.11 by weight of the active ingredient.
v. 3 parts by weight of the active ingredient No. 3.21 are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 31 by weight of the active ingredient,
VI. 20 parts by weight of the active ingredient No. 3.22 are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, B parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.
VII. 1 part by weight of the active ingredient No. 3.34 is dissolved in a mixture composed of 70 parts by weight of cyciohoxanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.

VIII. 1 part by weight of active ingredient No. 3.35 is dissoivea in a mixture composed of 80 parts by weight of eyelobexanone and 20 parts by weight of Wettol* EM 31 (■ nonionic emulsifier based on ethoxylated castor oil). This gives a stable emulsion concentrate.
The compounds of the formula I, or the herbicidal compositions comprising them, can be applied pre- or post-emergence. If the active ingredients are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spray apparatus, in such a way that fchey come into as little contact as possible, if any, with the leaves of the sensitive crop plants while reaching the leaves of undesirable plants which grow underneath, or the bare soil {post-directed, lay-by).
Depending on the intended aim of the control measures, the season, the target plants and the growth stage, the application rates of the compound of the formula I are from 0.001 to 3,0, preferably 0.01 to 1.0 kg/ha of active substanz (a.s.)-
To widen the spectrum of action and to achieve synergistic effects, the 3-heterocyclyl-substituted benzoyl derivatives of the formula I can be mixed and applied jointly with a large number of representatives of other groups of herbicidally or growth-regulatory active ingredients. Suitable components in mixtures are, for example, 1,2,4-thiadiazoles, l,3,4-thiadia2oles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, aryloxy-Zhetaryloxyalkanic acids and their derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(hetaroyl/axoyl)-l,3-cyclohexandiones, hetaryl aryl ketones, benzylisoxazolidinones, meta-CF3-phenyl derivatives, carbamates, quinolinecarboxylic acid and its derivatives, chloroacetanilides, cyclohexenone oxime ether derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofuranes, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones,
N-~phenya-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and hetaryloxyphenoxypropionic esters, phenylacetic acid ind its derivatives, 2-phenylpropionic acid and its derivatives, pyrazolas, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers.

sulfonamides, sulfonylureas, triazines, triazinones, triazolinones, triazolcarboxaraides and uracils.
Moreover, it may be advantageous to apply the compounds of the formula I, alone or in combination with other herbicides, in the form of a mixture with additional other crop protection agents, for example with pesticides or agents for controlling phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates can also be added.
Use Examples
The herbicidal action of 3-heterocyclyl-substituted benzoyl derivatives of the fomtula I was demonstrated by the following greenhouse experiments!
The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of humus as substrate. The seeds of the test plants were sown separately for each species.
For the pre-emergence treatment, the active ingredients, suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated gently to promote germination and growth and subsequently covered with transparent plastic hoods until the plants had rooted. This cover caused uniform germination of the test plants unless this was adversely affected by the active ingredients.
For the post-emergence treatment, the test plants were grown to a plant height of from 3 to 15 cm, depending on the plant habit, and only then treated with the active ingredients which had been suspended or emulsified in water. To this end, the test plants were either sown directly and grown in the same containers, or they were first grown separately as seedlings and transplanted into the test containers a few days prior to treatment. The rate of application for the post-emergence treatment was 31.2 or 15.6 g/ha a.s. (active substance).

Depending on the species, the plants were kept at from 10 to 25°c and 20 to 35°C, respectively. The test period extended over 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.
