R.sub.15 and R.sub.16, independently of one another, are hydrogen or C.sub.1 -C.sub.5 alkyl, in free form or in salt form, and, if appropriate, to the tautomers thereof, in free form or in salt form, to a process for the preparation and to the use of these compounds and tautomers, to pesticidal compositions whose active ingredient is selected from these compounds and tautomers, in each case in free form or in the form of agrochemically utilisable salts, to a process for the preparation and to the use of these compositions, to plant propagation material treated with these compositions, to a method of controlling pests, to intermediates, in free form or in salt form, for the preparation of these compounds, and, if appropriate, to tautomers, in free form or in salt form, thereof, and to a process for the preparation and to the use of these intermediates.
Certain imidazole derivatives have been proposed in the literature as active ingredients in pesticides. However, the biological properties of these known compounds are not always entirely satisfactory in the field of pest control, resulting in a demand for other compounds with pesticidal properties, in particular for controlling insects and representatives of the order Acarina, this object being achieved according to the invention by providing the present compounds I.
Some of the compounds I can exist in the form of tautomers; for example, the compounds I, in which R.sub.3 is hydrogen, can be in equilibrium with those tautomers which have a --N.dbd.C(YH)--N(ZR.sub.4)-- group instead of the --NH--C(.dbd.Y)--N(ZR.sub.4)-- group. Accordingly, the compounds I hereinabove and hereinafter are, where appropriate, also to be understood as meaning corresponding tautomers, even when no specific mention is made of the latter in each individual case.
Compounds I which have at least one basic center can form, for example, acid addition salts. These acid addition salts are formed, for example, with strong inorganic acids, such as mineral acids, for example perchloric acid, sulfuric acid, nitric acid, nitrous acid, a phosphoric acid or a hydrophilic acid, with strong organic carboxylic acids, such as unsubstituted or substituted, for example halogen-substituted, C.sub.1 -C.sub.4 alkanecarboxylic acids, for example acetic acid, or unsaturated or saturated dicarboxylic acids, for example oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid or phthalic acid, or hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or benzoic acid, or with organic sulfonic acids, such as unsubstituted or substituted, for example halogen-substituted, C.sub.1 -C.sub.4 alkane- or arylsulfonic acids, for example methane- or p-toluenesulfonic acid. Compounds I which have at least one acidic group can furthermore form salts with bases. Suitable salts with bases are, for example, metal salts such as alkali metal salts or alkaline earth metal salts, for example sodium salts, potassium salts or magnesium salts, or salts with ammonia or with an organic amine, such as morpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower-alkylamine, for example ethyl-, diethyl-, triethyl- or dimethylpropylamine, or a mono-, di- or trihydroxy-lower-alkylamine, for example mono-, di- or triethanolamine. Moreover, corresponding internal salts may also be formed, where possible. Preferred salts within the scope of the invention are agrochemically advantageous salts; however, the invention also comprises salts which are disadvantageous for agochemical purposes, for example salts which are toxic to honey bees or fish and which are employed, for example, for isolating or purifying free compounds I or agrochemically utilisable salts thereof. Due to the close relationship between the compounds I in free form and in the form of the salts thereof, the free compounds I, or the salts thereof, are to be understood analogously hereinabove and hereinafter as meaning, if appropriate, also the corresponding salts and the free compounds I, respectively. The same applies to tautomers of compounds I and salts thereof. Generally preferred is, in each case, the free form.
Unless otherwise defined, the general terms used hereinabove and hereinafter have the meanings given below.
Halogen, as a group per se and as structural element of other groups and compounds, such as haloalkyl, is fluorine, chlorine, bromine or iodine, in particular fluorine, chlorine or bromine, especially fluorine or chlorine.

Alkyl, as a group per se and as structural element of other groups and compounds, such as haloalkyl, alkoxy, alkylthio, alkylamino, dialkylamino and N-alkyl-N-alkoxy-amino-carbonyl, is, in each case with due consideration of the number of carbon atoms contained in each case in the particular group or compound, either straight-chain, i.e. methyl, ethyl, propyl, butyl or pentyl, or branched, for example isopropyl, isobutyl, sec-butyl, tert-butyl, isopentyl or neopentyl.
Alkenyl and alkynyl are straight-chain or branched and contain in each case two or, preferably, one unsaturated carbon-carbon bond(s). The double or triple bonds of these substituents are preferably separated from the remaining part of the compound I by at least one saturated carbon atom. Examples which may be mentioned are allyl, methallyl, but-2-enyl, but-3-enyl, propargyl, but-2-ynyl and but-3-ynyl.
Haloalkyl, can be partially halogenated or perhalogenated, where, in the case of a polyhalogenation, the halogen substituents can be identical or different. Examples of haloalkyl are methyl which is mono- to trisubstituted by fluorine, chlorine and/or bromine, such as CHF.sub.2 or CF.sub.3 ; ethyl which is mono- to pentasubstituted by fluorine, chlorine and/or bromine, such as CH.sub.2 CF.sub.3, CF.sub.2 CF.sub.3, CF.sub.2 CCl.sub.3, CF.sub.2 CHCl.sub.2, CF.sub.2 CHF.sub.2, CF.sub.2 CF.sub.2 CFCl.sub.2, CF.sub.2 CHBr.sub.2, CF.sub.2 CHClF, CF.sub.2 CHBrF or CClFCHClF; propyl or isopropyl, each of which is mono- to heptasubstituted by fluorine, chlorine and/or bromine, such as CH.sub.2 CHBrCH.sub.2 Br, CF.sub.2 CHFCF.sub.3, CH.sub.2 CF.sub.2 CF.sub.3, CF.sub.2 CF.sub.2 CF.sub.3 or CH(CF.sub.3).sub.2 ; and butyl or an isomer thereof, each of which can be mono- to nonasubstituted by fluorine, chlorine and/or bromine, such as CF(CF.sub.3)CHFCF.sub.3, CF.sub.2 (CF.sub.2).sub.2 CF.sub.3 oder CH.sub.2 (CF.sub.2).sub.2 CF.sub.3.

A compound I, II or V which can be obtained according to the process or by a different method can be convened into a different compound I, II or V in a manner known per se by replacing one or more substituents of the starting compound I, II or V in the customary manner by (a) different substituent(s) according to the invention.
Thus, it is possible, for example,
to convert compounds I, in which --Z--R.sub.4 is --N.dbd.C(R.sub.15)--R.sub.4, into compounds I, in which --Z--R.sub.4 is --N(H)--C(H)(R.sub.15)--R.sub.4,
to convert compounds I or II, in which R.sub.16 is hydrogen, into compounds I or II, in which R.sub.16 is other than hydrogen,
to convert compounds I, II or V, in which R.sub.3 is hydrogen, into compounds I, II or V, in which R.sub.3 is other than hydrogen, and
to convert compounds I, II or V, in which Y is O, into compounds I, II or V, in which Y is other than O.
Depending on which reaction conditions and starting materials are selected as being suitable for this purpose, it is possible to replace, in one reaction step, only one substituent by a different substituent according to the invention, or several substituents can be replaced in the same reaction step by other substituents according to the invention.
Salts of compounds I, II and V can be prepared in a manner known per se. For example, acid addition salts of compounds I, II and V are obtained by treating them with a suitable acid or a suitable ion-exchanger reagent, and salts with bases an obtained by treating them with a suitable base or a suitable ion-exchanger reagent.
Salts of compounds I, II and V can be converted in the customary manner into the free compounds I, II and V, for example acid addition salts by being treated with a suitable basic agent or a suitable ion-exchanger reagent, and salts with bases, for example, by being treated with a suitable acid or a suitable ion-exchanger reagent.
Salts of compounds I, II and V can be converted in a manner known per se into different salts of compounds I, II and V, for example acid addition salts into different acid addition salts, for example by treating a salt of an inorganic acid, such as a hydrochloride, with a suitable metal salt, such as a sodium salt, barium salt or silver salt, of an acid, for example using silver acetate, in a suitable solvent, in which an inorganic salt which is being formed, for example silver chloride, is insoluble and so separates out from the reaction mixture.
Depending on the procedure and the reaction conditions, the compounds I, II and V which have salt-forming properties can be obtained in free form or in the form of salts.
The compounds I, II and V and in each case, if appropriate, the tautomer thereof, in each case in free form or in salt form, can be present in the form of one of the isomers which are possible or as a mixture of these, for example as pure isomers, such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures, depending on the number and the absolute and relative configuration of asymmetric carbon atoms in the molecule and/or depending on the configuration of non-aromatic double bonds in the molecule; the invention relates to the pure isomers and to all isomer mixtures which are possible and is to be understood accordingly in each case hereinabove and hereinafter, even when stereochemical details are not mentioned specifically in each individual case.
Diastereomer mixtures and racemate mixtures of compounds I, II or V, in free form or in salt form, which can be obtained according to the process--depending on which starting materials and procedures are selected--or by other routes, can be separated on the basis of the physicochemical differences of the components in the known manner to give the pure diastereomers or racemates, for example by fractional crystallisation, distillation and/or chromatography.
Enantiomer mixtures which can be obtained accordingly, such as racemates, can be resolved by known methods to give the optical antipodes, for example by recrystallisation from an optically active solvent, by chromatography on chiral adsorbents, for example high-pressure liquid chromatography (HPLC) on acetylcellulose, with the aid of suitable microorganisms, by cleavage using specific, immobilised enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer is complexed, or by conversion into diastereomeric salts, for example by reacting a basic end-product racemate with an optically active acid, such as a carboxylic acid, for example camphoric acid, tartaric acid or malic acid, or a sulfonic acid, for example camphoric sulfonic acid, and separating the resulting mixture of diastereomers, for example by fractional crystallisation since they differ with regard to their solubility properties, to give the diastereomers, from which the enantiomer desired can be liberated by allowing suitable agents, for example bases, to act on them.
Pure diastereomers or enantiomers can be obtained according to the invention not only by separating suitable isomer mixtures but also by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process according to the invention using stereochemically suitable educts.
If the individual components differ with regard to their biological activity, it is advantageous to isolate, or synthesis, in each case the biologically more effective isomer, for example enantiomer or diastereomer, or isomer mixture, for example enantiomer mixture or diastereomer mixture.
The compounds I, II and V, in free form or in salt form, can also be obtained in the form of their hydrates and/or can also include other solvents, for example solvents which may be used for crystallising compounds in solid form.
The invention relates to all those embodiments of the process in which, starting from a starting material or intermediate which can be obtained in any desired step of the process, all or some of the missing steps are carried out or a starting material is used in the form of a derivative or salt thereof and/or the racemates or antipodes thereof or, in particular, formed under the reaction conditions.
Starting materials and intermediates, in each case in free form or in salt form, which are used in the process of the present invention are preferably those which lead to the compounds I which have been described at the outset as being particularly valuable, or to salts thereof.
The invention particularly relates to the preparation processes described in Examples H1 to H16.
The invention furthermore relates to starting materials and intermediates, in each case in free form or in salt form, which are novel and which are used according to the invention for the preparation of the compounds I or salts thereof, to a process for their preparation and to their use as starting materials and intermediates for the preparation of the compounds I; in particular, this applies to the compounds I, II and V.
The compounds I according to the invention are valuable as preventive and/or curative active ingredients in the field of pest control, even at low rates of application, and have a highly favourable biocidal spectrum while being well tolerated by warm-blooded species, fish and plants. The active ingredients according to the invention are active against all or individual development stages of normally sensitive, but also resistant, animal pests, such as insects or representatives of the order Acarina. The insecticidal or acaricidal activity of the active ingredients according to the invention can in this case become apparent either directly, i.e. from a destruction of the pest which occurs either immediately or only after some time has elapsed, for example during moulting, or indirectly, for example from reduced oviposition and/or hatching rates, the good activity corresponding to a mortality rate of not less than 50 to 60%.

The active ingredients according to the invention allow pests of the abovementioned type which can be found, in particular, on plants, especially useful plants and oronmentals in agriculture, horticulture and silviculture, or on parts of such plants, such as fruits, flowers, foliage, stalks, tubers or roots, to be controlled, i.e. contained or destroyed, and in some cases the protection against the pests extends to parts which are formed at a later point in time.
Target crops which are possible are, in particular, cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar beet or fodder beet; fruit, for example pomaceous fruit, stone fruit and soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; legnminous plants, such as beans, lentils, peas or soya beans; oil crops, such as oilseed rape, mustard, poppies, olives, sunflowers, coconuts, castor, cocoa or groundnuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrous fruits, such as oranges, lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes or bell peppers; species from the laurel family, such as avocado, cinnamon or camphor, and tobacco, nuts, coffee, egg plants, sugar cane, tea, pepper, grapes, hops, species from the banana family, latex plants and ornamentals.
The active ingredients according to the invention are particularly suitable for controlling Aphis craccivora, Bemisia tabaci, Myzus persicae, Nephotettix cincticeps and Nilaparvata lugens in vegetable, fruit and rice crops.
Other fields of application for the active ingredients according to the invention are the protection of stored products and stores and of material and, in the hygiene sector, in particular the protection of domestic animals and productive livestock against pests of the abovementioned type.
The invention therefore also relates to pesticidal compositions, such as emulsifiable concentrates, suspension concentrates, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, wettable powders, soluble powders, dispersible powders, dusts, granules or encapsulations in polymeric substances, all of which comprise at least one of the active ingredients according to the invention and are to be selected depending on the intended aims and the prevailing circumstances.
In these compositions, the active ingredient is used as a pure active ingredient, for example a solid active ingredient in a specific particle size or, preferably, together with at least one of the auxiliaries conventionally used in the an of formulation, such as extenders, for example solvents or solid carriers, or such as surface-active compounds (surfactants).
The following are examples of suitable solvents: partially hydrogenated or unhydrogenated aromatic hydrocarbons, preferably the fractions C.sub.8 to C.sub.12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffins or cyclohexane, alcohols, such as ethanol, propanol or butanol, glycols and their ethers and esters, such as propylene glycol, dipropylene glycol ether, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents, such as N-methylpyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, or water, epoxidized and unepoxidized vegetable oils, such as epoxidized and unoxidized rapeseed oil, castor oil, coconut oil or soya oil, and silicone oils.
Solid carriers which are used, for example for dusts and dispersible powders, are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silicas or highly-disperse absorptive polymers. Possible particulate, adsorptive carriers for granules are either porous types, for example pummice, brick grit, sepiolite or bentonite, or non-sorptive carrier materials, for example calcite or sand. Moreover, a large number of granulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues.
Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient to be formulated. The surfactants listed hereinbelow are in this case only to be regarded as examples; a large number of other surfactants conventionally used in the an of formulation and suitable according to the invention are described in the specialist literature.
Suitable non-ionic surfactants are mainly polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can have 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl radical of the alkylphenols. Other suitable non-ionic surfactants are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylene diaminopolypropylene glycol and alkyl polypropylene glycol which have 1 to 10 carbon atoms in the alkyl chain and 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. The abovementioned compounds customarily have 1 to 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Other substances which are suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.
The cationic surfactants are mainly quaternary ammonium salts which have, as substituents, at least one alkyl radical having 8 to 22 C atoms and, as further substituents, lower, halogenated or unhalogenated alkyl, benzyl or lower hydroxyalkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples are stearyltrimethylammonium chloride and benzyldi(2-chloroethyl)ethylammonium bromide.
Suitable artionic surfactants can be either water-soluble soaps or water-soluble, synthetic surface-active compounds. Soaps which are suitable are the alkali metal salts, alkaline earth metal salts and substituted or unsubstituted ammonium salts of higher fatty acids (C.sub.10 -C.sub.22), such as the sodium salts or potassium salts of oleic or stearic acid, or of natural mixtures of fatty acids which can be obtained, for example, from coconut oil or tall oil; the fatty acid methyltaurates must also be mentioned. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates and fatty sulfates are, as a rule, in the form of alkali metal salts, alkaline earth metal salts or substituted or unsubstituted ammonium salts and have, as a rule, an alkyl radical having 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals, for example the sodium salt or the calcium salt of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives have preferably 2 sulfonyl groups and one fatty acid radical having approximately 8 to 22 C atoms. Alkylarylsulfonates are, for example, the sodium salts, calcium salts or triethanolammonium salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensation product. Suitable phosphates, such as salts of the phosphoric ester of a p-nonylphenol-(4-14)ethylene oxide adduct, or phospholipids, are also suitable.
As a rule, the compositions comprise 0. 1 to 99%, in particular 0. 1 to 95%, of active ingredient and 1 to 99.9%, in particular 5 to 99.9%, of--at least--one solid or liquid auxiliary, it being possible, as a rule, for 0 to 25%, in particular 0. 1 to 20%, of the composition to be surfactants (% in each case meaning per cent by weight). While concentrated compositions are more preferred as commercially available goods, the end consumer uses, as a rule, dilute compositions with considerably lower concentrations of active ingredients. Preferred compositions are, in particular, composed as follows (%=per cent by weight):
Emulsifiable concentrates:
______________________________________Emulsifiable concentrates:Active ingredient: 1 to 90%, preferably 5 to 20%Surfactant: 1 to 30%, preferably 10 to 20%Solvent: 5 to 98%, 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 24%, 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 99%, preferably 15 to 98%Granules:Active ingredient: 0.5 to 30%, preferably 3 to 15%Solid carrier: 99.5 to 70%, preferably 97 to 85%______________________________________
The activity of the compositions according to the invention can be broadened considerably and adapted to prevailing circumstances by adding other insecticidal active ingredients. Representatives of the following active ingredient classes are examples of suitable additions of active ingredients: organophosphorus compounds, nitrophenols and derivatives, formamidines, acrylureas, carbamates, pyrethroids, nitroenamines and derivatives, pyrrols, thioureas and derivatives, chlorinated hydrocarbons and Bacillus thuringiensis preparations. The compositions according to the invention can also comprise other solid or liquid auxiliaries, such as stabilizers, for example epoxidized or unepoxidized vegetable oils (for example epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, and also fertilizers and other active ingredients for achieving specific effects, for example acaricides, bactericides, fungicides, nematocides, molluscicides or selective herbicides.
The compositions according to the invention are prepared in a known manner, in the absence of auxiliaries, for example by grinding, screening and/or compressing a solid active ingredient or active ingredient mixture, for example to give a certain particle size, and in the presence of at least one auxiliary, for example, by intimately mixing and/or grinding the active ingredient or active ingredient mixture with the auxiliary or auxiliaries. The invention also provides these processes for the preparation of the compositions according to the invention and the use of the compounds I for the preparation of these compositions.
The invention also provides the methods of application for the composition, i.e. the methods for controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, seed-dressing, scattering or pouring, depending on the intended aims and the prevailing circumstances, and the use of the compositions for controlling pests of the abovementioned type. Typical rates of application are between 0.1 and 1,000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The rates of application per hectare are, as a rule, 1 to 2,000 g of active ingredient per hectare, in particular 10 to 1,000 g/ha, preferably 20 to 600 g/ha.
A preferred method of application in the field of crop protection is application to the foliage of the (plant foliar application), where frequency and rate of application will depend on the risk of infestation with the pest in question. However, the active ingredient can also reach the plants via the root system (systemic action) by drenching the locus of the plants with a liquid composition or incorporating the active ingredient into the locus of the plants, for example into the soil, in solid form, for example in the form of granules (soil application). In paddy rice, such granules can be metered into the flooded paddy field.
The compositions according to the invention are also suitable for protecting plant propagation material, for example seed, such as fruits, tubers or kernels, or plant cuttings, against animal pests. The propagation material can in this case be treated with the composition before planting, for example seed can be dressed before sowing. The active ingredients according to the invention can also be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of solid composition. The composition can also be applied to the site of application when the propagation material is planted, for example when it is sown into the seed furrow. The invention also provides these treatment methods for plant propagation material and the plant propagation material which has been treated in this manner.

The Examples which follow are not limiting, but only intended to illustrate the invention. Temperatures are given in degrees celsius.
PREPARATION EXAMPLES
Example H 1: 2,3-Dihydro-2-oxo-3-tert-butylcarbonylmethyl-5-trifluoromethyl-1,3,4-oxadiazole.
15 g of Nail dispersed in oil (80%) are washed with petroleum ether until free from oil and treated with 125 ml of N,N-dimethylformamide. A mixture of 77 g of 2,3-dihydro-2-oxo-5-trifluoromethyl-1,3,4-oxadiazole and 250 ml of N,N-dimethylformamide is added dropwise to this suspension in the course of an hour at room temperature. The reaction mixture is stirred for 3 hours, 72.5 g of chloromethyl tert-butyl ketone are added, and the mixture is stirred for a further 16 hours at room temperature and then evaporated. The residue is treated with 1 l of water, and the product which has precipitated is filtered off with suction and dried. This gives the title compound in the form of colourless crystals which melt at 69.degree.-71.degree..
Example H2: 1-Acetylamino-2,3-dihydro-3,4-dimethyl-2-oxo-1H-imidazole (compound no. 1.5 in table 1).
68.5 ml of aqueous methylamine solution (40%) are added dropwise to a solution of 78 g of 3-acetylmethyl-2,3-dihydro-5-methyl-2-oxo-1,3,4-oxadiazole in 500 ml of acetonitrile. After the slightly endothermal reaction has subsided, the orange mixture is stirred-for 30 minutes at 48.degree. and then evaporated. The residue is treated with 100 ml of tetrahydrofuran and 200 ml of ethyl acetate, during which process crystals precipitate. The crystals are filtered off, washed with ethyl acetate and dried under reduced pressure at 60.degree.. This gives a mixture of 1-acetylamino-2,3-dihydro-3,4-dimethyl-2-oxo-1H-imidazole and 1-acetylamino-3,4-dimethyl-4-methylamino-2-oxo-imidazolidine. A sample of this mixture is separated on silica gel using ethyl acetate/methanol (2:1) as eluent, yielding the pure 1-acetylamino-2,3-dihydro-3,4-dimethyl-2-oxo-1H-imidazole which melts at 199.degree.-201.degree. and the pure 1-acetylamino-3,4-dimethyl-4-methylamino-2-oxo-imidazolidine which melts with decomposition at 150.degree.-152.degree.. Another sample of the above-mentioned mixture is heated to 175.degree. and held at this temperature until the evolution of methylamine gas has ceased. The residue is cooled and stirred with a small amount of methanol. Filtration of the suspension gives the pure title compound melting after drying at 199.degree.-201.degree..

Example H8: 2,3-Dihydro-3-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-4-tert-butyl-1H-imidazole (compound no. 9.2 in table 9).
4.3 g of 3-formylpyridine and two drops of concentrated hydrochloric acid are added to a solution of 6.8 g of 1-amino-2,3-dihydro-3-methyl-2-oxo-4-tert-butyl-1H-imidazole in 50 ml of ethanol. The reaction mixture is refluxed for 30 minutes with stirring and then substantially concentrated. The liquid residue is dissolved in a small amount of diethyl ether, and the solution is cooled to 0.degree.. The crystals which have separated out are filtered off with suction and dried. This gives the title compound which melts at 116.degree.-121.degree..
Example H9: 2,3-Dihydro-2-oxo-1-pyrid-3-ylmethyleneamino-4-tert-butyl-1H-imidazole (compound no. 9.1 in table 9).

The reaction mixture is refluxed for 30 minutes with stirring and then cooled to room temperature, upon which the mixture starts to crystallize. To complete the crystal precipitation process, 100 ml of diethyl ether are added to the mixture. The crystallizate is filtered off with suction, triturated with acetonitrile, again filtered off with suction and then dried. This gives the title compound which melts at 255.degree.-256.degree..
Example H10: 2,3-Dihydro4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole (compound no. 4.1 in table 4).
A solution of 156 g of 3-acetylmethyl-2,3-dihydro-5-methyl-2-oxo-1,3,4-oxadiazole in 600 ml of acetonitrile is treated with 170 g of aqueous ammonia solution (30%), and the mixture is stirred for one hour at 80.degree. in an autoclave. A pressure of approximately 8 bar is in this case established. The resulting suspension is evaporated, the residue is dissolved in 500 ml of methanol, and 40 g of gaseous HCl are passed into the solution at 50.degree.. The reaction mixture is stirred for 30 minutes at 50.degree., and 107 g of 3-formylpyridine are then added dropwise at the same temperature. The reaction mixture is stirred for a further 30 minutes at 50.degree., then cooled to 0.degree., and filtered with suction. The filter cake, consisting of 2,3-dihydro-2-oxo-1-pyrid-3-ylmethyleneamino-4-tert-butyl-1H-imidazole hydrochloride (compound no. 4.1.1 in table 4), is dissolved in water at room temperature. The pH of the solution is brought to approximately 7 using aqueous sodium hydroxide solution (30%), during which process a precipitation of crystals is observed at a pH of approximately 3. The crystals are filtered off with suction and dried in vacuo, yielding the title compound melting at 200.degree.-202.degree..
Example H11: 2,3-Dihydro-3,4-dimethyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imizadole hydrochloride (compound no. 4.2.1 in table 4).
8.2 g of 3-formylpyridine are added to a suspension of 11.4 g of 1-amino-2,3-dihydro-3,4-dimethyl-2-oxo-1H-imidazole hydrochloride in 40 ml of ethanol. The reaction mixture is stirred for 14 hours and then filtered, and the filter cake is washed with a small amount of cold ethanol and dried, yielding the title salt melting above 240.degree..
Example H12: 2,3-Dihydro-3,4-dimethyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole (compound no. 4.2 in table 4).
12.6 g of 2,3-dihydro-3,4-dimethyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole hydrochloride are dissolved in 150 ml of water. The solution is saturated with sodium chloride and treated with 100 ml of tetrahydrofuran. The mixture is then rendered weakly alkaline using aqueous sodium hydroxide solution (30%). The phases are separated, and the aqueous phase is extracted nine times using in each case 100 ml of tetrahydrofuran. The combined tetrahydrofuran phases are dried using magnesium sulfate and evaporated, yielding the rifle compound in the form of yellow crystals melting at 186.degree.-187.degree..
Example H13: 2,3-Dihydro-3-ethylcarbonylmethyl-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole (compound no. 4.14 in table 4).
0.72 g of sodium hydride are added to a suspension of 4.1 g of 2,3-dihydro-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole in 80 ml of N,N-dimethylformamide. The mixture is heated to 50.degree., treated with a solution of 3.78 g of 1-bromo-2-oxo-butane in 20 ml of N,N-dimethylformamide, and stirred for 30 minutes. The N,N-dimethylformamide is then removed on a rotary evaporator. In a mixer, the residue is mixed intimately with water. The crystals are filtered off, yielding the title compound melting at 183.degree.-184.degree..
Example H14: 3-Cyanomethyl-2,3-dihydro-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole (compound no. 4.25 in table 4).
0.72 g of sodium hydride are added to a suspension of 4.1 g of 2,3-dihydro-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole in 80 ml of N,N-dimethylformamide. The mixture is heated to 50.degree., treated with a solution of 1.89 g of chloroacetonitrile in 20 ml of N,N-dimethylformamide, and stirred for 30 minutes. The N,N-dimethylformamide is then removed on a rotary evaporator. In a mixer, the residue is mixed intimately with water. The crystals are filtered off, yielding the title compound melting at 195.degree.-198.degree..
Example H15: 2,3-Dihydro-3-(4-ethoxycarbonylbut-1-yl)-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole (compound no. 4.29 in table 4).
0.72 g of sodium hydride are added to a suspension of 4.1 g of 2,3-dihydro-4-methyl-2-oxo-1-pyrid-3-ylmethyleneamino-1H-imidazole in 80 ml of N,N-dimethylformamide. The mixture is heated to 50.degree., treated with a solution of 5.22 g of 1-bromo-4-ethoxy-carbonyl-butane in 20 ml of N,N-dimethylformamide, and stirred for 30 minutes. The N,N-dimethylformamide is then removed on a rotary evaporator. The residue is treated with ethyl acetate, during which process sodium bromide precipitates. The mixture is filtered over Celite, and the filtrate is evaporated. The residue is treated with hexane, during which process crystals precipitate. The crystals are filtered off with suction and dried yielding the title compound melting at 74.degree.-76.degree..
