The inventive compounds of General formula (I) in which n represents 1 or 2, can be obtained from corresponding compounds of General formula (I) in which n represents 0, using the method known in the art, such as reaction with a suitable oxidizing agent. Suitable oxidants are, for example, hypochlorites, organic percolate, such as m-perchlorobenzene acid and peracetic acid, inorganic chemicals, such as ozone, chlorine, hydrogen peroxide, periodate sodium, perborate sodium, potassium permanganate and oxygen in the air.

The claimed compounds can be used in conventional compositions in fo the Subject of the invention is therefore also herbicide agent, which contains at least one compound of formula (I).

The compounds of formula (I) can be introduced into the compositions of various types, depending on which biological and/or physico-chemical parameters are provided. As possible type formulations may, for example, be considered sprayable powders (WP), water-soluble powders (SP), water-soluble concentrates, emulsifiable concentrates (EC), emulsions (EW) such as oil-in-water" or "water in oil", solutions for spray, concentrated suspensions (CS), dispersions on an oil or water-based, mixed with oil solutions, suspensions for capsules (CS), funds in the form of dust (DP), etching tools, granules for spreading and deposition on soil, granules (GR) in the form of microgranules, granules spray, granules for Elevator and adsorption granules, dispersible in water and granules, water-soluble granules (WG), ULV formulations, microcapsules and compounds in the form of wax (mastic).

These separate types of trains in principle known and described, for example,, "Chemische Technologie", Band 7, C. Hauser Verlag, 4. Aufl. 1986, Wade van Valkenburg, "Pesticide Formulations", Marcel Dekker, N. Y. , 1973; K. Martens, "Spray Drying" Handbook, 3rd ed., 1 the crystals, surfactants, solvents and additional additives are also known and described, for example, in Watkins, "Handbook of Insecticide Dust Diluents and Carriers", 2nd ed., Darland Books, Caldwell N. J., H. V. Olphen, "Introduction to Clay Colloid Chemistry", 2nd ed., J. Willey & Sons, N. Y.; C. Marsden, "Solvents Guide", 2nd ed., Interscience, N. Y., 1963; McCutcheon''s "Detergents and Emulsifiers Annual", MC Publ. Corp., Ridgewood N. J. ; Sisley and Wood, "Encyclopedia of Surface Active Agents", Chem. Publ. Co. Inc., N. Y., 1964;, "Grenzflachenaktive Athylenoxidaddukte", Wiss. Verlagsgesell. , Stuttgart, 1976; Winnacker-, "Chemische Technologie", Band 7, C. Hauser Verlag, 4. Aufl., 1986.

On the basis of these compounds may be obtained as a combination with other substances, active as pesticides, such as insecticides, acaricides, herbicides, fungicides, and also with protective equipment, mineral fertilizers and/or growth regulators, for example, in the form of a solid composition or in the form of commercial mixtures.

Powders for spraying are also dispersible in water preparations, which, along with the active component, in addition to diluents and inert substance, also contain surfactants of ionic and/or nonionic type (wetting and dispersing agents), for example, polyoxyethylene ALKYLPHENOLS, polyoxyethylenated residues of fatty polyhydric alcohols, alkanesulfonyl, alkylbenzenesulfonate, sodium salt ligninsulfonate acid, sodium salt of 2,2'- dynafilter-6,6'-disulfonate, sodium salt of dibutylaminoethanol or sodium salt oleoylethanolamide acid (taurine). To obtain a sprayable powder active ingredients (herbicides) finely pulverized, for example, in conventional apparatuses such as hammer mills, blower mills or air-jet mills, and simultaneously or after the above-mentioned process is mixed with part of assistive technology.

Emulsifiable concentrates are obtained by dissolving the active ingredients in an organic solvent, for example butanol, cyclohexanone, dimethylformamide, xylene or high-boiling aromatic solvents or hydrocarbons or mixtures of organic solvents with addition of one or more surfactants of ionic and/or nonionic type (emulsifiers). As emulsifiers can be used, for example, calcium salt alkylarylsulfonates, such as qualitydetermination, or nonionic emulsifiers, such as polyglycolide esters of fatty acids, alkylaryl, alkalemia polyethers, esters sorbitan, such as esters sorbitan and fatty acids or polyoxyethylene esters sorbitan, for example polyoxyethylene esters sorbitan and fatty acids.

Fine powders (means in the form of dust) can be obtained by grinding the active ingredient with finely powdered solid substances, for example talc, natural clays such as kaolin, bentonite or pyrophyllites, or hard-shelled land.

The concentrated suspensions can be water or oil based. They can be obtained, for example, by wet grinding using conventional mills and in some cases with the addition of surface-active substances, such as already described above for other types of structures.

Emulsions, for example, emulsion oil in water (EW), can be obtained, for example, with agitators (mixers), colloid mills and/or static mixers using aqueous organic solvents and, in some cases, surface-active substances, such as, for example, has already been described above for other types of structures.

The granules can be obtained either by spraying the active components capable of adsorption, granulated inert material, or ipolyarray.h acids or mineral oils, on the surface of carriers such as sand, kaolinites or granulated inert material. Suitable active ingredients may also be granulomatosa usual to obtain a granular manner, optionally in a mixture with fertilizers.

Dispersible in water pellets, usually obtained by conventional technologies, such as spray drying, spray granulation in the vortex layer (flow), disk granulation, mixing in high-speed mixers and extrusion without solid inert material.

About getting disc granules fluidized granules, pellets made by extrusion and spray see, for example, the way in "Spray-Drying Handbook", 3rd ed., 1979, G. Goodwin Ltd., London; J. E. Browning, "Agglomeration", Chemical and Engineering 1967, Seiten 147 ff; "Perry's Chemical Engineer''s Handbook", 5th ed., McGraw-Hill, New York, 1973, s. 8-57.

Additional details regarding the composition of plant protection products see, for example, in G. C. Kingman, "Weed Control as a Science", John Wiley and Sons, Inc. , New York, 1961, Seiten 81-96 and J. D. Freyer, S. A. Evans, "Weed Control Handbook", 5th ed., Blackwell Scientific Publications, Oxford, 1968, Seiten 101-103.

Agrochemical compositions contain, as a rule, from 0.1 to 99 wt.%, in particular from 0.1 to 95 wt.%, the active substance of the formula (I).

In powders for spraying concentration act out of the ordinary ingredients of the composition. In the case of emulsifiable concentrates, the concentration of the active substance can be from 1 to 90 wt.%, preferably from 5 to 80 wt.%. Fine compositions contain from 1 to 30 weight. % of active substance, preferably mainly from 5 to 20 wt.% the active substance, spray solutions contain from about 0.05 to 80 weight. %, preferably from 2 to 50 wt.%, the active substance. In case dispersible in water and granules, the active substance depends partly on whether the active compound is liquid or solid and what granular auxiliary tool which fillers and so forth are used. For granules, dispersible in water, the active substance is, for example, between 1 and 95 wt.%, preferably between 10 and 80 weight. %.

Along with this, these compositions containing the active substance, in some cases, contain conventional current funds for adhesion, wetting, dispersing agents, emulsifiers, penetration means (penetrants, preservatives, antifreeze agents, solvents, fillers, carriers and colorants, defoamers, substances that prevent evaporation, and tools that affect the pH and viscosity.

The inventive compounds of General formula (I) exhibit excellent is s (weeds). On hard eradicates perennial weeds, which allowed shoots from rhizomes, roots or other long-lasting parts, also good are the active components. Still, information on whether the connection to the appropriate method before sowing, before germination or after germination. In particular, it should be called, for example, some representatives of one - and dicotyledonous weed flora, the growth of which can be controlled using the claimed compounds, although, based on the names, it is not necessary to impose restrictions on certain other types.

From among the monocotyledonous weed species action compounds are, for example, Avena, Lolium, Alopecurus, Phalaris, Echinochloa, Digitaria, Setaria and Cyperus (ground almonds) from the annual group, and from among the perennial species, Agropyron, Cynodon, Imperata and Sorghum and also perennial Cyperus species.

In dicotyledonous weed species, the spectrum of action extends, for example, on species of Galium, Viola, Veronica, Lamium, Stellaria, Amaranthus, Sinapis, Ipomoea, Matricaria, Abutilion and Sida from the number of annual weeds, and nvolvulus, Cirsium, Rumex and Artemisia in perennial weeds.

When the specific conditions of cultivation of crops with weeds found in rice, such as Echinochloa, Sagittaria, Alisma, Eleocharis, S applied to the soil surface before germination, either the germination of embryos of completely suppressed weeds, or weeds only grow to the level of embryonic shoots, then comes their growth, and, in the end, they completely die within 3-4 weeks after germination.

When applying the active compounds in green parts of plants after germination sudden growth also comes very quickly after the treatment, and the weed stop at the stage of growth at which they were at the time of application, or die off after a certain time, and thus very early and permanently eliminates harmful to cultivated plants competition.

Despite the fact that the claimed compounds exhibit pronounced herbicide activity in relation to one - and dicotyledonous weeds, crop plants of economic important crops such as wheat, barley, rye, rice, maize, sugar beet, cotton and soya, are not significantly damaged or not damaged at all. For these reasons, the presented compounds are very well suited for the selective combating undesirable plant growth in the cultivation of useful agricultural crops and ornamental plants.

On the basis of their herbicide properties of the active substance can be and the ski modified plants still subject to development. Transgenic plants have, as a rule, are particularly useful properties, such as resistance to certain pesticides, especially to certain herbicides, resistance to plant diseases or pathogens of plant diseases such as certain insects or microorganisms such as fungi, bacteria or viruses. Other distinguishing characteristics include, for example, fruits, namely, their quantity, quality, capacity for long-term storage, composition and special ingredients. So, for example, known transgenic plants with increased starch content or a changed amount of starch or plants with a different composition of fatty acids in the fruit.

Preferred is the use of the inventive compounds of the formula (I) in the cultivation of economically important transgenic crops of useful and ornamental plants, for example cereals such as wheat, barley, rye, oats, millet, rice, manioc and corn, or other crops of sugar beet, cotton, soybean, rapeseed, potato, tomato, peas and other vegetables.

Preferably, the inventive compounds of General formula (I) can be used as herbicides in Vostochnyi in santehnicheskie changes.

The traditional way of getting new plants which have modified properties compared to conventional plants, consists, for example, in the classical way of excretion and the production of mutants. Alternative new plants with modified properties can be generated using santehnichekogo method (see , for example, European patent application EP-A 0221044, EP-A 0131624). In some cases, are described, for example,
hentainiches changes of cultivated plants in order to modify synthesized in plants starch (for example, International application WO 92/11376, WO 92/14827, WO 91/19806),
transgenic crop plants which are resistant to certain herbicides of the type of glufosinate (see, for example, European patent application EP-A 0242236, EP-A 0242246) or glyphosate (international application WO 92/00377) or sulfonylureas (European patent application EP-A 0257993, U.S. patent US-A 5013659),
transgenic crop plants, for example cotton, with the ability to produce Bacillus Thuringian toxins (Bt toxins) which make the plants resistant to certain pests (European patent application EP-A 0142924, EP-A 0193259),
transgenic plants with modified of train is Yu, which can be obtained new transgenic plants with modified properties, in principle known (see, for example, Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2. Aufl. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, or Winnacker "Gene und Klone", VCH Weinheim 2. Edition, 1996, or Christou, "Trends in Plant Science" 1 (1996), 423-431). For such santehnicheskie manipulation of the nucleic acid molecule can be introduced into plasmids which allow mutagenesis or changing sequences due to recombination of DNA sequences. Using the above standard methods can occur, for example, the exchange of reasons, to leave part of the sequences or to add natural or synthetic sequences. To link the DNA fragments to each other on the fragments can sit down adapters or links.

Obtaining plant cells with a reduced activity of geneproduct can be achieved, for example, using the expression of at least one corresponding antisense RNA (antisense-RNA), one sense RNA (sense-RNA) to achieve compressional effect or expression of at least one suitably constructed ribozyme which specifically cleaves transcripts of the abovementioned reproductiv. Besides can be used combined DNA molecules, which include the common code is likely DNA which include only part of the coded sequence, with the parts must be of sufficient length to cause the cells antisense (antisense) effect. You can also use sequences of DNA that have a high degree of gomologichnosti to coded sequences of geneproduct, but not identical.

When the expression of nucleic acid molecules in plants are synthesized protein can be localized in any compartment of plant cells. But in order to achieve localization in a particular compartment, it is possible, for example, to associate the encrypted region with DNA sequences which ensure localization in a particular compartment. Such sequences are known (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al. , Proc. Natl. Acad. Sci., USA 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106).

Transgenic plant cells can be regenerated by known technologies in whole plants. In the case of transgenic plants fundamentally we can talk about plants of any kind, that is, as monocots and dicots. So can be obtained transgenic plants which exhibit modified properties due to overexpression, suppression or inhibition of homologous is Preferably the inventive compounds of General formula (I) can be used in transgenic crops, which are resistant to herbicides from the group including sulfonylureas, glufosinate ammonium or (and) picofast of Isopropylamine, and analogous active substances.

The use of the claimed active substances in transgenic crops, along with the action on the weeds observed in other cultures, there are also actions that are specific for use in the current transgenic crops, for example a modified or specifically the expected range (set) weeds which can be controlled, changed number, which can be used for application, preferably good ability in combination with herbicides, which is resistant transgenic crops and the impact on the growth and yield of transgenic crops.

Depending on external conditions such as temperature, humidity, the type of herbicide, among other things varies expenditure required amount of the inventive compounds of General formula (I). It can vary within wide limits, for example between 0.001 and 10.0 kg/ha of active substance or more, preferably it lies between 0.005 and 5 kg/ha
