Compounds to be named are especially

3-chloro-2-[4-chloro-2-fluoro-5-(1-dimethylamino-1-methylethoxycarbonyl)phenyl]-4,5,6,7-tetrahydro-1H-indazole and
3-chlor-2-[4-chloro-2-fluoro-5-(2-ethylthio-1-methylethoxycarbonyl)phenyl]-4,5,6,7-tetrahydro-2H-indazole.
The compounds of the formula I can be prepared by
a) esterification of a carbonic acid derivative of the formula II, wherein R.sup.1, R.sup.2 and W are as defined above and R.sup.5 is hydroxyl, chlorine or bromine, with an alcohol of the formula III, wherein A and Q are as defined above ##STR12## The starting material of the formulae II and III are known or can be produced in analogy to processes known from the literature.
The carbonic acid derivatives of the formula II, necessary for the synthesis of the pyrazoles, indazoles respectively cyclopenta[c]pyrazoles of the formulae Ia, Ib respectively Ic are described in the published European Patent application EP-A-0,138,527.
EP-A-0,104,532 relates to pyrrolo[1,2-c]imidazol-1,3-diones and imidazo[1,5-a]pyridin-1,3-diones of the formula II, which can be used as starting material for the production of the compounds of formula Id and Ie.
EP-A-0,104,484 further discloses pyrazol-[1,2-a][1,2,4]triazol-1,3-diones and 1,2,4-triazolo[1,2-a]pyrazidin-1,3-diones of the formula II, which can be used in the process according to the invention as starting material for the production of the end-products of the formulae If and Ig.
Processes for the production of the starting material of formula II are also disclosed in the European Patent Application No. 89810438.8.
The published European Patent applications EP-A-0,104,538 and EP-A-0,104,484 relate predominantly to simple esters of the formula II (R.sup.5 is optionally substituted alkoxy). From these ester can be prepared, e.g. by saponification, optionally followed by chlorination or bromination (e.g. with POCl.sub.3 or POBr.sub.3) the free carbonic acid (R.sup.5 =OH) or the acid chlorides respectively bromides (R.sup.5 =Cl or Br) of the formula II.
The esterification reactions according to the invention are processes known to the skilled in the art.
The condensation of the acid chlorides respectively acid bromides of formula II with the alcohols of the formula III is advantageously conducted in a solvent that is inert to the reaction, at a temperature ranging from 0.degree. C. to the boiling point of the solvent, especially until about 120.degree. C. Thereby it can be advantageous to use bases, which bind the liberated HCl respectively HBr.
It is also possible to esterify directly the free carbonic acids of the formula II (R.sup.5 =OH) Then water-splitting resp. water-binding agents are needed. Water-splitting acids are e.g. protonic acids. As water-binding agents are to be mentioned especially carbodiimides, such as cyclohexyl carbodiimide.
The reaction-processes, starting from the carbonic acids of the formula II are also conducted advantageously in a solvent which is inert to the reaction, at temperatures of from 0.degree. C. and about 100.degree. C.
If the carbodiimide method is used, low temperatures of from 0.degree. C. to about room temperature are preferred.
The compounds of the formula I", wherein W, R.sup.1, R.sup.2, R.sup.3 and A are as defined above and Q is --S(O).sub.m -R.sup.3 and m is 1 or 2, can be prepared by oxidation of the thioesters of the formula I' ##STR13## wherein W, R.sup.1, R.sup.2, R.sup.3 and A is as defined above and m is zero.
These oxidations are preferably conducted in solvents at temperatures of from 0.degree. C. to 100.degree. C.
Such oxidations are known to the skilled in the art. They are described among other in Houben Weyl, "Methoden der Organischen Chemie" Vol. IX, page 211 ff. Appropriate oxidation agents are hydrogenperoxide or peracids such as e.g. m-chloroperbenzoic acid or potassium permanganate in glacial acetic acid e.g. analogous to J. Am. Chem. Soc. 63 (1941) p. 1971 or Can. J. Chem. 57 (1979) p. 2426.
The compounds of formula I are highly active active ingredients for plants that at suitable rates of application are excellently suitable as selective herbicides for controlling weeds in crops of useful plants. That is to say, at such rates of application the active ingredients of formula I are distinguished by a good selective herbicidal property against weeds. Culture plants, such as rye, barley, oats, wheat and maize, sorghum, rice, cotton and soybeans remain virtually undamaged at low rates of application. At increased rates of application the growth of the crop plants is influenced only to a small extent. If the rates of application are very high, the substances of formula I have total herbicidal properties.
The selective herbicidal activity of the compounds of the invention is observed both in pre-emergence and post-emergence application. These compounds can therefore be used with equal success pre- or post-emergence in selective weed control. The compounds of this invention are suited especially for pre-emergent application in the following crops: barley, wheat, maize, rice, sorghum, soya, cotton and sun-flowers and for post-emergent application in the following cultures: barley, wheat, maize, rice and sorghum.
Advantageously, the compounds or compositions of the invention can be applied also to the propagation material of the crop plant. Seed dressing, especially, may be mentioned here. Propagation material is seeds, plantlets or other parts of the plant from which the crop plants can be reared. The invention also relates to the propagation material treated with an effective amount of a compound of formula I.
The invention relates also to herbicidal compositions that contain a novel compound of formula I, and to methods for pre-and post-emergence weed control.
The compounds of formula I are used in unmodified form or, preferably, in the form of compositions together with the adjuvants conventionally employed in the art of formulation, and are therefore formulated in known manner e.g. into emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.
The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant or extender, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents or extenders are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether, ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.
The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues.
Depending on the nature of the compound of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also be understood as comprising mixtures of surfactants.
Both so-called water-soluble soaps and also water-soluble synthetic surface-active compounds are suitable anionic surfactants.
Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C.sub.10 -C.sub.22), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tallow oil. Mention may also be made of fatty acid methyltaurin salts.
More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and contain a C.sub.8 -C.sub.22 alkyl radical which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of lignosulfonic acid, of dodecylsulfate or of a mixture of fatty alcohol sulfates obtained from natural fatty acids.
These compounds also comprise the salts of sulfated and sulfonated fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a condensate of naphthalenesulfonic acid and formaldehyde.
Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of ethylene oxide, or phospholipids.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 10 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.
Further suitable non-ionic surfactants are the water-soluble adducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol containing 1 to 10 carbon atoms in the alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit.
Examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.
Fatty acid esters of polyoxyethylene sorbitan, e.g. polyoxyethylene sorbitan trioleate, are also suitable non-ionic surfactants.
Cationic surfactants are preferably quaternary ammonium salts which contain, as N-substituent, at least one C.sub.8 -C.sub.22 alkyl radical and, as further substituents, unsubstituted or halogenated lower alkyl, benzyl or hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.
Surfactants customary in the art of formulation are described, inter alia, in the following publications:
"1986 International Mc Cutcheon's Emulsifiers and Detergents", Glen Rock, N.J., USA, 1986; H. Stache "Tensid Taschenbuch", 2nd edition, C. Hanser Verlag, Munich/Vienna, 1981; M. and J. Ash. "Encyclopedia of Surfactants", Vol. I-III, Chemical Publishing Co., N.Y., 1980-1981.
The active ingredient preparations usually contain 0.1 to 95 %, preferably 0.1 to 80%, of a compound of formula I, 1 to 99.9% of one or more solid or liquid adjuvants, and 0 to 25% of a surfactant.
Preferred formulations are composed especially as follows (throughout, percentages are by weight)
______________________________________Emulsifiableconcentrates:active ingredient 1 to 20%, preferably 5 to 10%surfactant 5 to 30%, preferably 10 to 20%liquid carrier 50 to 94%, preferably 70 to 85%.Dusts:active ingredient 0.1 to 10%, preferably 0.1 to 1%solid carrier 99.9 to 90%, preferably 99.9 to 99%.Suspension concentrates:active ingredient 5 to 75%, preferably 10 to 50%water 94 to 25%, preferably 88 to 30%surfactant 1 to 40%, preferably 2 to 30%.Wettable powders:active ingredient 0.5 to 90%, preferably 1 to 80%surfactant 0.5 to 20%, preferably 1 to 15%solid carrier 5 to 95%, preferably 15 to 90%.Granulates:active ingredient 0.5 to 30%, preferably 3 to 15%solid carrier 99.5 to 70%, preferably 97 to 85%.______________________________________
Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations. The formulations can be diluted to a concentration as low as 0.001 % active ingredient.
The compositions may also contain further additives such as stabilisers, antifoams, viscosity regulators, binders, tackifiers and also fertilisers or other active ingredients for obtaining special effects.
The following Examples illustrate the invention.

EXAMPLES
H.1.1. Production of 3-chloro-2-{4-chloro-2-fluoro-5 [1-methyl-2-(1-methylethyl thio)-ethoxycarbonyl]-phenyl}-4,5,67,7-tetrahydro-2H-indazole
A solution of 3.5 g of 3-chloro-2-(4-chloro-2-fluoro-5-chlorocarbonylphenyl)-4,5,6,7-tetrahy dro-2H-indazole in 50 ml of toluene is added dropwise at room temperature to a stirred solution of 1.4 g of (1-methylethyl)thiopropan-2-ol and 1.5 ml of triethylamine in 50 ml of toluene. After everything is added, the reaction mixture is stirred for another 3 hours at room temperature. The triethylamine-hydrochloride is then filtered off and the filtrate is concentrated under vacuum.
Thus 3.1 g of the title-compound of the formula ##STR14## can be isolated as an oil with a refractory index n.sub.D.sup.24 =1.5526 (compound No. 1.05).

B. BIOLOGICAL EXAMPLES
EXAMPLE B1
Pre-emergence herbicidal action
In a greenhouse, immediately after sowing the test plants in seed trays the surface of the soil is treated with an aqueous dispersion of the test compound. An application rate of active ingredient/hectare of 4 kg/ha is tested. The seed trays are kept in the greenhouse at 22.degree.-25.degree. C. and 50-70% relative humidity and the test is evaluated after 3 weeks.
The herbicidal action is assessed using a linear nine-stage evaluation scale, wherein 1 stands for total damage of the test plants (100% herbicidal action) and 9 for no herbicidal action (The test plant grows like an untreated plant used as reference).
Results are compiled in table 13.

EXAMPLE B3
Herbicidal action in paddy
The water weeds Echinochloa crus galli and Monocharia vag. are sown in plastics beakers (60 cm surface area, 500 ml volume). After sowing, the beakers are filled to the soil surface with water. 3 days after sowing, the water level is raised to slightly above (3-5 mm) the surface of the soil. Application is carried out 3 days after sowing by spraying an aqueous emulsion of the test substances onto the vessels at a rate of application of 250 g of active ingredient per hectare. The plant beakers are then placed in a greenhouse under optimum growth conditions for the rice weeds, i.e. at 25.degree.-30.degree. C. and high humidity. The tests are evaluated 3 weeks after the application.
The herbicidal action is assessed according to the scheme given in Example B1.
The test results are compiled in Table 15.
