The sulphonyl halides or sulphonic anhydrides of the formula (III) are known and/or can be prepared by processes known per se (cf. J. Org. Chem. 33 (1968), 2104; J. Org. Chem. 25 (1960), 1824; DE-AS (German Published Specification) 2,308,262; EP-OS (European Published Specifications) 23,140, 23,141, 23,422, 35,893, 48,143, 51,466, 64,322, 70,041, 44,808 and 44,809; U.S. Pat. Nos. 2,929,820, 4,282,242; 4,348,220 and 4,372,778 and Angew. Chem. 93 (1981), 151).
The process (a) according to the invention for the preparation of the new compounds of the formula (I) is preferably carried out using diluents. Suitable diluents in this process are virtually all inert organic solvents. These preferably include aliphatic and aromatic, optionally halogenated hydrocarbons, such as pentane, hexane, heptane, cyclohexane, petroleum ether, benzine, ligroin, benzene, toluene, xylene, methylene chloride, ethylene chloride, chloroform, carbon tetrachloride, chlorobenzene and o-dichlorobenzene, ethers, such as diethyl ether and dibutyl ether, glycol dimethyl ether, diglycol dimethyl ether, tetrahydrofuran and dioxane, ketones, such as acetone, methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone, esters, such as methyl acetate and ethyl acetate, nitriles, such as, for example, acetonitrile and propionitrile, amides, such as, for example, dimethylformamide, dimethylacetamide and N-methyl-pyrrolidone, and also dimethyl sulphoxide, tetramethylene sulphone, hexamethylphosphoric triamide and pyridine.
Acid acceptors which can be employed in the process (a) according to the invention include all the acidbinding agents which can customarily be used for reactions of this type. Alkali metal hydroxides, such as, for example, sodium hydroxide and potassium hydroxide, alkaline earth metal hydroxides, such as, for example, calcium hydroxide, alkali metal carbonates and alkali metal alkoxides, such as sodium carbonate and potassium carbonate, sodium tert.-butoxide and potassium tert.-butoxide, furthermore aliphatic, aromatic or heterocyclic amines, for example triethylamine, trimethylamine, dimethylaniline, dimethylbenzylamine, pyridine, picoline, 1,5-diazabicyclo-[4,3,0]-non-5-ene (DBN), 1,8-diazabicyclo-[5,4,0]-undec-7-ene (DBU) and 1,4-diazabicyclo[2,2,2]-octane (DABCO) are preferably suitable.
Catalysts which can be used in the process according to the invention are metal halides, such as, for example, aluminum chloride or zinc chloride.
When carrying out process (a) according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the process is carried out at temperatures from -50.degree. C. to +50.degree. C., preferably at temperatures from -40.degree. C. to +40.degree. C.
For carrying out process (a) according to the invention, 1 to 5 moles, preferably 1 to 4 moles, of sulphonyl halide or sulphonic anhydride of the formula (III) are generally employed per mole of aminoazole of the formula (II). If disulphonylated compounds of the formula (I,R.sup.2 =--SO.sub.2 --R.sup.1) are to be prepared in a one-pot reaction, at least 2 moles of sulphonyl halide or sulphonic anhydride (III) are to be employed per mole of aminoazole (II).
The reactants can be combined in any desired sequence. In a preferred embodiment of the process according to the invention, the starting substances of the formulae (II) and (III) are stirred at room temperature with a diluent, the mixture is cooled, if appropriate, and the acid acceptor is slowly metered into this mixture. The reaction mixture is then stirred until the reaction is complete.
If appropriate, the mixture is concentrated and/or diluted with a virtually water-immiscible organic solvent, such as, for example, methylene chloride, and working up can be carried out in a customary manner, for example by washing with water, drying, filtering and carefully removing the solvent from the filtrate by distillation. The crude product which remains in the residue can be purified further in a customary manner, for example by column chromatography and/or recrystallization.
The compounds which can be obtained as described above, of the formula (I) in which R.sup.2 stands for the grouping --SO.sub.2 --R.sup.1, can be reacted to give compounds of the formula (I) in which R.sup.2 stands for hydrogen by a reaction with desulphonylating agents, if appropriate in the presence of diluents.
In this connections, desulphonylating agents are taken to mean substances which are able to eliminate a sulphonyl grouping from N,N-bis-sulphonyl-amino compounds. Suitable desulphonylation agents are, above all, alkali metal hydroxides or alkaline earth metal hydroxides, such as sodium hydroxide, potassium hydroxide and calcium hydroxide, alkali metal alkoxides, such as sodium methoxide, potassium methoxide, sodium ethoxide and potassium ethoxide, furthermore ammonia, alkylamines, such as methylamine, ethylamine, propylamine and butylamine, and also dialkylamines, such as dimethylamine and diethylamine. Ammonia is preferably employed as a desulphonylating agent.
The desulphonylation is preferably carried out in the presence of diluents. Apart from water, preferred diluents are polar organic solvents, such as methanol, ethanol, propanol, isopropanol, 2-methoxyethanol, 2-ethoxyethanol and dioxane.
The desulphonylation is generally carried out at temperatures from 0.degree. C. to 150.degree. C., preferably at temperatures from 20.degree. C. to 100.degree. C.
For desulphonylation, the reactants are generally mixed at room temperature and, if appropriate, stirred at an increased temperature until the reaction is complete. If appropriate for working up, the mixture is concentrated, diluted with water and acidified with a strong acid, such as, for example, hydrochloric acid. During this process, the product (I, R.sup.2 =H) is obtained in the form of crystals and can be isolated by filtering off with suction.
Formulae (IVA) and (IVB) provide general definitions of the sulphonylated aminoguanidines to be used as starting substances in process (b) according to the invention for the preparation of compounds of the formula (I).
In the formulae (IVA) and (IVB), R.sup.1, R.sup.4, X, Y and Z preferably, or in particular, have those meanings which have already been preferably mentioned above, or mentioned above as particularly preferred, for R.sup.1, R.sup.4, X, Y and Z in connection with the description of the compounds of the formula (I) according to the invention.

The compounds of the formula (XIII) are known and/or can be prepared by processes known per se (cf. EP-A 5,986, EP-A 24,215, EP-A 121,082, EP-A 172,957, EP-A 173,321, EP-A 173,956, EP-A 224,078, DE-OS (German Published Specification) 3,634,928, DE-OS (German Published Specification) 3,634,929).
The sulphonylated aminoguanidines of the formula (IVB) were hitherto unknown from the literature and form the subject of the present invention. The new sulphonylated aminoguanidines of the general formula (IVB) are obtained when their isomer compounds of the formula (IVA)--above--are rearranged by stirring with a polar solvent, such as, for example, methanol, ethanol, propanol, isopropanol and/or water, at temperatures from 0.degree. C. to 150.degree. C.
In order to prepare the compounds of the formula (IVB), it is also possible to generate the isomers of the formula (IVA) as described above and to rearrange them in situ, i.e., without intermediate isolation.
Formula (V) provides a general definition of the ester(amide)s also to be used as starting substances in process (b) according to the invention for the preparation of compounds of the formula (I).
In formula (V), R.sup.3 preferably, or in particular, has the meaning which has already been preferably mentioned above, or mentioned above as particularly preferred, for R.sup.3 in connection with the description of the compounds of the formula (I) according to the invention, R preferably stands for C.sub.1 -C.sub.4 -alkyl, in particular for methyl or ethyl, and Q.sup.1 preferably stands for C.sub.1 -C.sub.4 -alkoxy or di-(C.sub.1 -C.sub.2 -alkyl)-amino, in particular for methoxy, ethoxy or dimethylamino.
Examples of the starting substances of the formula (V) which may be mentioned are: N,N-dimethylformamide dimethyl acetal and N,N-dimethylformamide diethyl acetal, trimethyl orthoformate and triethyl orthoformate, trimethyl orthoacetate and triethyl orthoacetate.
The compounds of the formula (V) are known chemicals for synthesis.
Process (b) according to the invention is preferably carried out in the presence of a diluent. In addition to the diluents indicated in process (a), alcohols, such as methanol, ethanol, propanol or isopropanol, are also particularly suitable as diluents in process (b).
When carrying out process (b) according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the process is carried out at temperatures from 0.degree. C. to 150.degree. C., preferably at temperatures from 10.degree. C. to 100.degree. C.
Process (b) according to the invention is generally carried out under atmospheric pressure. However, it is also possible for the process to be carried out under increased or reduced pressure.
For carrying out process (b) according to the invention, the starting substances required in each case are generally employed in approximately equimolar amounts. However, it is also possible to use one of the two components employed in each case in a relatively large excess. The reactions are generally carried out in a suitable diluent, and the reaction mixture is stirred for several hours at the temperature required in each case. Working up in process (b) according to the invention is in each case carried out by customary methods.
Formula (VI) provides a general definition of the substituted aminopyrazolines to be used as starting substances in process (c) according to the invention for the preparation of compounds of the formula (I).
In formula (VI), R.sup.4, X, Y and Z preferably, or in particular, have those meanings which have already been preferably described above, or described above as particularly preferred, for R.sup.4, X, Y and Z in connection with the description of the compounds of the formula (I) according to the invention.
Examples of the starting substances of the formula (VI) are listed in Table 5 below.

The starting substances of the formula (VI) were hitherto unknown from the literature. The compounds of the formula (VI) are obtained when hydrazinoazines of the formula (IX) ##STR342## in which R.sup.4, X, Y and Z have the abovementioned meanings,
are reacted with acrylonitrile in the presence of a base, such as, for example, sodium methoxide, potassium methoxide, sodium ethoxide and/or potassium ethoxide, and in the presence of a diluent, such as, for example, methanol and/or ethanol, at temperatures from 0.degree. C. to 100.degree. C.
Furthermore, process (c) according to the invention is carried out using sulphonyl halides or sulphonic anhydrides (III). As far as the starting substances for process (c) are concerned, the data of the compounds of the formula (III) provided above in the description of the starting substances of process (a) are applicable.
Process (c) according to the invention is preferably carried out using diluents.
Suitable diluents are virtually all inert organic solvents, as they have been mentioned above in process (a) according to the invention.
If appropriate, process (c) is carried out in the presence of an acid acceptor. Suitable acid-binding agents are above all those which have been mentioned above in process (a).
When carrying out process (c) according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the process is carried out at temperatures from -50.degree. C. to +50.degree. C., preferably at temperatures from -40.degree. C. to +40.degree. C.
For carrying out process (c) according to the invention, 1 to 5 moles, preferably 1 to 4 moles, of sulphonyl halide or sulphonic anhydride of the formula (III) are generally employed per mole of aminopyrazoline of the formula (VI). If disulphonylated compounds of the formula (I, R.sup.2 =--SO.sub.2 --R.sup.1) are to be prepared in a one-pot reaction, at least 2 moles of sulphonyl halide or sulphonic anhydride (III) are to be employed per mole of aminopyrazoline (VI).
The reactants can be combined in any desired sequence. In a preferred embodiment of process (c) according to the invention, the starting substances of the formulae (VI) and (III) are stirred at room temperature with a diluent, the mixture is cooled, if appropriate, and the acid acceptor is slowly metered into this mixture. The reaction mixture is then stirred until the reaction is complete.
Working up and (if appropriate) desulphonylation can be carried out as described above in process (a).
If desired, salts can be prepared from the compounds of the general formula (I) according to the invention. Such salts are obtained in a simple manner by customary salt formation methods, for example by dissolving or dispersing a compound of the formula (I) in a suitable solvent, such as, for example, water, methanol, ethanol or acetone, and adding a suitable acid or base. If appropriate, the mixture is stirred for a relatively long time, and the salts can then be isolated by concentrating or filtering off with suction.
The active compounds according to the invention can be used as defoliants, desiccants, agents for destroying broad-leaved plants and, especially, as weed-killers.. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are undesired. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.
The active compounds according to the invention can be used, for example, in connection with the following plants:
Dicotyledon weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver and Centaurea.
Dicotyledon cultures of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.
Monocotyledon weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.
Monocotyledon cultures of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.
However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.
The compounds are suitable, depending on the concentration, for the total combating of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for combating weeds in perennial cultures, for example forests, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana platations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hop fields, and for the selective combating of weeds in annual cultures.
The active compounds can be converted to the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.
These formulations are produced in known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is emulsifying agents and/or dispersing agents and/or foam-forming agents.
In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkyl naphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, as well as water.
As solid carriers there are suitable: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silicic acid, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, corn cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example non-ionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as albumin hydrolysis products; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

PREPARATION EXAMPLES
EXAMPLE 1 (IA-1) ##STR343##
26.1 g (0.1 mol) of methyl 2-chlorosulphonylbenzoate are added to a solution of 4.75 g (0.025 mol) of 1-(4,6-dimethyl-pyrimidin-2-yl)-3-amino-triazole in 100 ml of methylene chloride, the mixture is cooled to -5.degree. C., and 11.2 g (0.1 mol) of diazabicyclo[2.2.2]octane, dissolved in 40 ml of methylene chloride, are added dropwise at -5.degree. C. to 0.degree. C. The reaction mixture is stirred for 2 days at room temperature (20.degree. C.) and then washed with water; the methylene chloride phase is separated off, dried over sodium sulphate, filtered and concentrated. The oily residue can be crystallized using ethyl acetate.
The residue is filtered off with suction and dried, and 6.6 g (45% of theory) of 1-(4,6-dimethylpyrimidin-2-yl)-3-(N,N-bis-(2-methoxycarbonyl-phenylsulphonyl))-aminotriazole remain as colorless crystals of melting point 209.degree.-212.degree. C.
EXAMPLE 2 (IA-2) ##STR344##
1.17 g (0.002 mol) of 1-(4,6-dimethyl-pyrimidin-2-yl)-3-(N,N-bis-(2-methoxycarbonyl-phenylsulphonyl))aminotriazole are stirred at reflux temperature (about 70.degree. C.) overnight in a mixture of 10 ml of 25% strength ammonia water and 10 ml of ethanol. In this process, the substance dissolves completely. The batch is concentrated and the residue is diluted with 30 ml of water. A pH of 3 is adjusted with hydrochloric acid and the product is filtered off with suction, washed and dried.
0.7 g (90% of theory) of 1-(4,6-dimethyl-pyrimidin-2-yl)-3-(2-methoxycarbonyl-phenylsulphonyl)aminotriazole in the form of colorless crystals of melting point 215.degree. C.-217.degree. C. is obtained.
