 7 Claims, N0 Drawings The present invention relates to and has for its objects the provisions of particular new O-( l-halophenyl- 2-chloro)-viny1-phosphoric acid diester-amides, e.g. O-alkyl--(l-monoto f-penta-halophenyl-2-chloro)- vinyl-phosphoric a&#39;eid diester-amides wherein the nitrogen atom may be singly or doubly substituted, which possess insecticidal, acaricidal, fungicidal and bactericidal properties, active compositions in the form of mixtures of such compounds with solid and liquid dispersible carrier vehicles, and methods for producing such compounds and for using such compounds in a new way especially for combating pests, e.g. insects, aearids, fungi and bacteria, especially insects, acarids and fungi, with other and further objects becoming apparent from a study of the within specification and accompanying examples. I  
  It is known from German Published Specification DAS Nos. 1,215,137 and 1,198,605, and U.S. Pat. No. 3,102,842 that vinylphosphoric acid triesters, such as 0,0-dimethyl-(Compound A) or 0,0-diethyl-0-[ 1- (2,4&#39;-dichlorophenyl)-2-chlorovinyl]- (Compound B) phosphoric acid esters (Compounds C and D), possess insecticidal and acaricidal properties.  
  The present invention provides vinylphosphoric acid diester-amides of the general formula Preferably, R is straight-chain or branched alkyl of l to carbon atoms, chloroethyl, allyl, alkoxyalkyl of l to 4 carbon atoms per alkyl and alkoxy moiety, phenyl, chlorophenyl, phenylalkyl of 1 to 3 carbon atoms in the alkyl moiety, cyclohexyl, p-methylcyclohexyl, eyclohexylmethyl, cyclohexylethyl or cyclohex-( 1 )-en- 4-yl-methyl; R and.R&#34;.are hydrogen, straight-chain or branched alkyl of l to 4 carbon atoms, allyl or benzyl 6 or together with the nitrogen atoms, form a fivemembered or six-membered heterocyclic ring optionally including an oxygen, sulfur or additional nitrogen atom; Hal is chlorine; and n is 2 or 3.  
  Surprisingly, the vinylphosphoric acid diester-amides according to the invention display a better insecticidal, especially soil insecticidal, acaricidal and fungicidal action than previously known compounds of analogous structure and similar type of action. The compounds according to the present invention thus represent a genuine enrichment of the art. Furthermore, the new substances contribute to meeting the great demand for constantly new preparations in the field of combating of pests. This demand arises from the fact that the commercially available agents have to meet constantly higher standards especially with regard to the protection ,of the environment, such as low toxicity towards warm-blooded animals and low phytotoxicity, rapid degradation in and on the plant in short intervals between application and harvesting, and activity towards resistant pests.  
  The general formula (1) encompasses the corresponding cisand trans-isomers of the structures (11) and (III) as well as mixtures of these isomers:  
  O I H R 01 R C /N C v n H Rn Q 01 Hal Hal (II) (III) The invention also provides a process for the production of a vinylphosphoric acid diester-amide of the structure (1) in which a vinylphosphoric acid ester dichloride of the general formula in the form of an alkali metal salt, alkaline earth metal salt or ammonium salt or in the presence of an acidbinding agent, and the resulting intermediate, generally without isolation, is reacted with ammonia or an amine of the general formula in the presence of an acid-binding agent. In the abovementioned formulae R, R, R&#34;, Hal and n have the meanings indicated DOS No. 2,137,383 and DAS No. 1,263,748). The following are specific examples of suitable starting substances: l-(2,4-dichlorophenyl)-2-chlorovinyl]- or 0-[ l-(2,4,5-trichlorophenyl)-2-chlorovinyl]- phosphoric acid ester dichloride.  
  The process for the production of the new compounds (I) is preferably carried out in the presence of earlier. a solvent or diluent. As such, practically all inert or- If 0-l -d or ph ny )-2- y l0 ganic solvents can be employed. Preferred examples phosphoric acid este dichloride. methanol and y include aliphatic and aromatic optionally chlorinated amine are used as starting materials, the course of the h d b h as benzene, toluene, Xylene, b reaction can be represented by the following reaction zine, methylene chloride, chloroform, carbon tetrascheme: chloride, chlorobenzene; ethers, for example diethyl 0 Cl o oca Cl-CH=C-OP HUGH -CH=C-0-.P

  The following are specific examples of alcohols and amines for use in the process: methanol, ethanol, nand iso-propanol, n-, sec-, isoand tert.-butanol, pentanol, Z-methylbutanol, hexanol, Z-ethyl-butanol, 2,2- dimethylbutanol octanol, 2-ethylhexanol, 2,2- dimethylhexanol, decanol and 2,2-dimethyloctanol; allyl, chloroethyl, methoxyethyl, ethoxyethyl, propoxyethyl and butoxyethyl alcohols; phenol, pchlorophenol, phenethyl alcohol, methylphenylcarbinol, l-phenyl-propanol-(3), cyclohexanol, pmethylcyclohexanol, cyclohexylmethanol, B-cyclohexylethanol and cyclohex-(l)-en-4-yl-methanol; as well as ammonia, methylamine, dimethylamine, ethylamine, diethylamine, n-propylamine, iso-propylamine, di-npropylamine, di-iso-propylamine, n-butylamine. di-nbutylamine, iso-butylamine, di-iso-butylamine, secbutylamine, di-sec-butylamine, tert-butylamine, di-tertbutylamine, allylamine, benzylamine, pyrrolidine, piperidine, morpholine and thiomorpholine.  
  The vinylphosphoric acid ester dichlorides (IV) also required as starting materials can be prepared according to processes known in principle, for example from the corresponding halophenacyl chlorides and phosphorus oxychloride or from 0,0-dialkyl-O- vinylphosphoric acid triester derivatives and phosphorus pentachloride (see German Published Specification acetone, methyl ethyl ketone, methyl isopropyl ketone, methyl isobutyl ketone; and nitriles, such as acetonitrile, propionitrile.  
  All customary acid-binding agents can be used as acid acceptors. Alkali metal carbonates and alkali metal alcoholates, such as sodium carbonate and potassium carbonate, sodium methylate and potassium methylate, and sodium ethylate and potassium ethylate, have proved particularly suitable, as have aliphatic, aromatic or heterocyclic amines, for example triethylamine, dimethylamine, dimethylaniline, dimethylbenzylamine and pyridine. An excess of the particular amine (VI) used for the reaction can also serve as the acidbinding agent.  
  The reaction temperatue can be varied within a wide range. In general, the reaction is carried out at l0 to perferably at -5 to 40C in both process stages. The reaction is generally allowed to take place at normal pressure.  
  In most cases, the reactants are used in equimolar ratio. An excess of one or other component does not seem to result in an significant advantages.  
  In general, a solution of the alcohol (V) is added dropwise to a solution of the vinylphosphoric acid ester dichloride (W) at the indicated temperatures, in the presence of an acid-binding agent, the mixture is allowed to complete reacting for one to several hours and a solution of amine (VI) and fresh acid-binding agent is then added dropwise. After completion of the reaction, the salt-like precipitate which has separated out is either filtered off or washed out with water and the filtrate is worked up in the usual manner by washing, drying and concentration or distillation.  
  Some of the new compounds are obtained in the form of oils which cannot always be distilled withoutdecomposition but can be freed of the last volatile constituents by so-called slight distillation, that is prolonged heating under reduced pressure to moderately elevated temperature, and can be purified in this way. They are characterized by the refractive index. Others of the new compounds are obtained in a crystalline form having a sharp melting point.  
  As already mentioned, the new vinylphosphoric acid diester-amides are distinguished by an excellent insecticidal, especially soil-insecticidal and acaricidal, activity towards plant pests, hygiene pests and pests of stored products. They possess a good action both against sucking and against biting insects and mites (Acarina).  
  For this reason, the compounds according to the invention can be employed successfully as agents for combating pests, in plant protection and in the hygiene field and the field of protection of stored products.  
  To the sucking insects there belong, in the main aphids (Aphidae) such as the green peach aphid (Myzus persicae), the bean aphid (Doralis fabae), the bird cherry aphid (Rhopalosiplzum parli), the pea aphid (Macrosiplmm pisi) and the potatoe aphid (Maerosiphum solanifolii), the currant gall aphid (Cr \&#39;plom \&#39;zus korschelti), the rosy apple aphid (Sappaplris muli), the mealy plum aphid (Hyalopterus arundinis) and the cherry black-fly (Myzus cerusi); in addition, scales and mealybugs (Coccina), for example the oleander scale (Aspidiotus hederae) and the soft scale (Lecanium liesperidum) as well as the grape mealybug (Pseudoeoccus maritimus); thrips (Thysanoptera), such as Hereinathrips femoralis, and bugs, for example the beet bug (Piesma quadrala the red cotton bug (Dysdereus intermedius), the bed bug (Cimex Iectularius), the assassin bug (Rhodnius prolixus) and Chagas but (Triatoma in festans) and, further, cicadas, such as Euscelis bilobatus and Neoplwtettix biplmctatus.  
  In the case of the biting insects, above all there should be mentioned butterfly and moth caterpillars (Lepidoptera) such as the diamond-back moth (Plutella maculipennis), the gypsy moth (Lymantria dispar), the brown-tail moth (Euproctis c/rrysorrlzoea) and tent caterpillar (Malacosoma neusrria); further, the cabbage moth (Mamestra brassicae) and the cut-worm (Agrotis segetum), the large white butterfly (Pier-is brassicae), the small winter moth (Clzeimatobia brumata), the green oak tortrix moth (Torn-ix viridana), the fall armyworm (Laphygma frugiperda) and cotton worm (Prodenia litura), the ermine moth (Hyponomeum padella), the Mediterranean flour moth (Eplzestia kulmiella) and greater wax moth (Galleria mellonella).  
  Also to be classed with the biting insects are beetles (Coleoptera), for example the granary weevil (Siroplrilus granarius Calamlra granaria), the Colorado beetle (Leprinotarsa decemlineara), the dock beetle (Gastrophysu virirlula), the mustard beetle (Phaedon coclzleariae), the blossom beetle; (Meliget/zes aeneus), the raspberry beetle (Bylurus tomenrosus), the bean weevil (Brucliidius Acant/wscelides obtectus), the leather beetle (Dermesres frischi), the khapra beetle (Trogoderma granarium), the flour beetle (Tribolium -(Blaberus gigameus) and the black giant cockroach (Blaberus fuscus) as well as Hensc&#39;lwutedenia flexivitta; further, Orthoptera, for example the house cricket (Gryllus domestieus); termites such as the eastern subterranean termite (Reticulirermesflaripes) and Hymenopter a such as ants, for example the garden ant (Lasius niger).  
  The Diptera comprise essentially the flies, such as the vinegar fly (Dmsoplzila melanogaster), the Mediterranean fruit fly (Ceratitis capitata), the house fly (Musca domestica), the little house-fly (Famzia canieularis), the black blow fly (Plzormia aegina) and bluebottle fly (Calliplzora er \&#39;rliroeepllala) as well as the stable fly (Sromoxys calcirrans); further, gnats, for example mosquitoes such as the yellow fever. mosquito (Aedes aegypli), the northern house mosquito (Culex pipiens) and the malaria mosquito (Anopheles stepliensi).  
  With the mites.(Acari) there are classed, in particular, the spider mites (Tetranychidae) such as the twospotted spider mite (Tetranychus telarius Tetranyc/ms alrhaeae or Terranyclzus urricae) and the European red mite (Paratetranyelms pilosus Panonyc/ms,ulmi), .gall mites, for example the blackcurrant gall mite (Eriopliyes ribis) and tarsonemids, for example the broad mite (Hemirarsonemus latus) and the cyclamen mite (Tarsonemus pallidus); finally, ticks such as the relapsing fever tick (Ornitlwdorus mou bata).  
 When applied against hygiene pests and pests of stored products, particularly flies and mosquitoes, the compounds are also distinguished by an outstanding residual activity on wood and clay, as well as a good stability to alkali on limed substrates. 7 v The active compounds according to the invention furthermore display, as also already mentioned, a strong fungitoxic and a bacteriotoxic action. They do not harm crop plants in the concentrations required for combating fungi and bacteria and only have a low toxicity towards warm-blooded animals. For these reasons, they are also suitable forcombating&#39; fungi and bacteria and are employed as fungitoxic agents in plant protection, against Archimycetes, Phycomycetes, Asomycetes, Basidiomycetes and Fungi Imperfecti.  
  The active compounds according to the invention show a very broad spectrum of action and can therefore be employed against parasitory fungi and bacteria which attack parts of plants which are above ground. or those which attack the plants through the soil, and also against seed-borne pathogens.  
 The active compounds according to the invention have proved of especial value in combating diseases of fungi. Surprisingly, the new products not only possess a protective action but also a curative and systemic ef fect.  
  The components according to the invention however are also active against other fungi which attack rice plants or other crop plants, for example Cochliobolus myiabeanus, M \&#39;cosphaerella musicola, Cercospora personata, Botryris cinerae, Alternaira spec. Verticillium alboatrum, Phialophora cinerescens and Fusarium spec., as well as against the bacterium Xanthomonas oryzae.  
  The active compounds according to the instant invention can be utilized, if desired, in the form of the usual formulations or compositions with conventional inert (i.e. plant compatible or herbicidally inert) pesticide diluents or extenders, i.e. diluents, carriers or extenders of the type usable in conventional pesticide formulations or compositions, e.g. conventional pesticide dispersible carrier vehicles such as gases, solutions, emulsions, suspensions, emulsifiable concentrates, spray powders, pastes, soluble powders, dusting agents, granules, etc. These are prepared in known manner, for instance by extending the active compounds with conventional pesticide dispersible liquid diluent carriers and/or dispersible solid carriers optionally with the use of carrier vehicle assistants, e.g. conventional pesticide surface-active agents, including emulsifying agents and/or dispersing agents, whereby, for example, in the case where water is used as diluent, organic solvents may be added as auxiliary solvents. The following may be chiefly considered for use as conventional carrier vehicles for this purpose: aerosol propellants which are gaseous at normal temperatures and pressures, such as freon; inert dispersible liquid diluent carriers, including inert organic solvents, such as aromatic hydrocarbons (e.g. benzene, toluene, xylene, alkyl naphthalenes, etc.), halogenated, especially chlorinated, aromatic hydrocarbons (e.g. chlorobenzenes, etc.) cycloalkanes (e.g. cyclohexane, etc.), paraffins (e.g. petroleum or mineral oil fractions), chlorinated aliphatic hydrocarbons (e.g. methylene chloride, chloroethylenes, etc.), alcohols (e.g. methanol, ethanol, propanol, butanol, glycol, etc.) as well as ethers and esters thereof (e.g. glycol monomethyl ether, etc.), amines (e.g. ethanolamine, etc.), amides (e.g. dimethyl formamide, etc.), sulfoxides (e.g. dimethyl sulfoxide, etc.), acetonitrile, ketones (e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, etc.), and/or water; as well as inert dispersible finely divided solid carriers, such as ground natural minerals (e.g. kaolins, clays, alumina, silica, chalk, i.e. calcium carbonate, talc, attapulgite, montmorillonite, kieselguhr, etc.) and ground synthetic minerals (e.g. highly dispersed silicic acid, silicates, e.g. alkali silicates, etc.), whereas the following may be chiefly considered for use as conventional carrier vehicle assistants, e.g. surface-active agents, for this purpose: emulsifying agents, such as non-ionic and- /or anionic emulsifying agents (e.g. polyethylene oxide esters of fatty acids, polyethylene oxide ethers of fatty alcohols, alkyl sulfates, alkyl sulfonates, aryl sulfonates, albumin hydroyzates, etc., and especially alkyl arylpolyglycol ethers, magnesium stearate, sodium oleate, etc.), and/or dispersing agents, such as lignin, sulfite waste liquors, methyl cellulose, etc.  
  Such active compounds may be employed alone or in the form of mixtures with one another and/or with such solid and/or liquid dispersible carrier vehicles and/or with other known compatible active agents, especially plant protection agents, such as other insecticides, acaricides, fungicides and bactericides, or rodenticides, nematocides, herbicides, fertilizers, growth-regulating agents, etc., if desired, or in the form of particular dosage preparations for specific application made therefrom, such as solutions, emulsions, suspensions, powders, pastes, and granules which are thus ready for use.  
  As concerns commercially marketed preparations, these generally contemplate carrier compositions mixtures in which the active compound is present in an amount substantially between about 01-95% by weight, and preferably 05-90% by weight, of the mixture, whereas carrier composition mixtures suitable for direct application or field application generally contemplate those in which the active compound is present in an amount substantially between about 0.0001-l07c, preferably 0.0l-l7r, by weight of the mixture. Thus, the present invention contemplates over-all compositions which comprises mixtures of a conventional dispersible carrier vehicle such as (l) a dispersible inert finely divided carrier solid, and/or (2) a dispersible carrier liquid such as an inert organic solvent and/or water preferably including a surface-active effective amount of a carrier vehicle assistant, e.g. a surface-active agent, such as an emulsifying agent and/or a dispersing agent, and an amount of the active compound which is effective for the purpose in question and which is generally between about 0.00l-7c, and preferably 0.01-957c, by weight of the mixture.  
  The active compounds can also be used in accordance with the well known ultra-low-volume process with good success, i.e. by applying such compound if normally a liquid, or by applying a liquid composition containing the same, via very effective atomizing equipment, in finely divided form, e.g. average particle diameter of from 50-100 microns, or even less, i.e. mist form, for example by airplane crop spraying techniques. Only up to at most about a few liters/hectare are needed, and often amounts only up to about 15 to 1000 g/hectare, preferably 40 to 600 g/hectare, are sufficient. In this process it is possible to use highly concentrated liquid compositions with said liquid carrier vehicles containing from about 20 to about 95% by weight of the active compound or even the active substance alone, e.g. about 20-100% by weight of the active compound.  
 Furthermore, the ,present invention contemplates methods of selectively killing, combating or controlling pests, e.g. insects, acarids, fungi and bacteria, and more particularly methods of combating at least one of insects, acarids and fungi, which comprises applying to at least one of correspondingly (a) such insects, (b) such acarids, (e) such fungi, (d) such bacteria, and (e) the corresponding habitat thereof, i.e. the locus to be protected, a correspondingly combative or toxic amount, i.e. an insecticidally, acaricidally, fungicidally or bactericidally effective amount, of the particular active compound of the invention alone or together with a carrier vehicle as noted above. The instant formulations or composition are applied in the usual manner, for instance by spraying, atomizing, vaporizing, scattering, dusting, watering, squirting, sprinkling, pouring, fumigating, dressing, encrusting, and the like.  
  It will be realized, of course, that the concentration of the particular active compound utilized in admixture with the carrier vehicle will depend upon the intended application. Therefore, in Special cases it is possible to go above or below the aforementioned that the ranges.
